Primary Multiple Cerebral Hydatid Cyst in 8 Year-Old Girl: A Rare Cause of Childhood Seizure

Background: Cystic echinococcosis is a zoonotic infection that occurs worldwide. Humans are infected through ingestion of parasite eggs in contaminated food, water or through direct contact with infected dogs, which are the definite host. Humans serve accidentally as intermediate host, and occurrences are common in children and young adults. Cystic echinococcosis is endemic in Mediterranean, South American, Middle Eastern, Central Asia, East Africa countries and Australia. Multiple cerebral hydatid cysts are very rare with only a few reports in the literature. Case Description: We present the case of an 8-year-old girl who presented with focal seizures, hemiparesis, headache, vomiting and bilateral optic atrophy. Diagnostic workup was performed, and magnetic resonance imaging revealed multiple intracranial cysts predominantly in the right frontal region with significant mass effect. A total of 11 intracranial cysts were removed surgically, and the child recovered uneventfully. Conclusion: Neurosurgeons should keep hydatidosis in the list of differentials when evaluating patients with cystic diseases of the brain. Although the removal of such cysts is challenging, outcomes are excellent when cysts are evacuated without rupture and patients show complete resolution of symptoms.

Case of takotsubo cardiomyopathy after surgical treatment of liver hydatid cyst: A case report

BACKGROUND Takotsubo cardiomyopathy,also called apical ballooning syndrome,is a disease that is often triggered by stress factors in postmenopausal women and mimics acute coronary syndrome.The aim of this article is to draw attention to takotsubo cardiomyopathy after surgical treatment of liver hydatid cyst.CASE SUMMARY A 50-year-old diabetic and hypertensive female patient was evaluated preoperatively before general surgery for liver hydatid cyst,and no cardiac problems were found.The patient was discharged on the 3rd postoperative day without any postoperative complications.On postoperative day 5,the patient presented to the emergency department with fever,shortness of breath,chills,and shivering and was hospitalized with the diagnosis of pneumonia.The troponin levels remained high during follow-up.Echocardiography was performed on postoperative day 7,after which the patient was referred to a tertiary center with the diagnosis of non-ST-elevation myocardial infarction due to akinesia in the apical region.Coronary angiography performed at the tertiary center showed normal coronary anatomy,and the patient was diagnosed with takotsubo cardiomyopathy.CONCLUSION Takotsubo cardiomyopathy mimicking myocardial infarction without ST segment elevation may develop after surgical treatment of liver hydatid cyst.

Laparoscopic management of hydatid cysts using long ribbon gauze:An initial experience of 37 consecutive cases

Objective:The laparoscopic approach is becoming the standard of care for many surgical disorders.However,in the case of hydatid cysts,laparoscopic management is challenging due to the risk of spillage of hydatid fluid,which can cause an anaphylactic reaction and recurrence.Here,we report our initial experience with laparoscopic partial pericystectomy of hydatid cysts using long ribbon gauze to decrease intra-operative spillage.Method:This was a retrospective study(between January 2010 and December 2021)in the Department of Surgical Gastroenterology,Sanjay Gandhi Postgraduate Institute of Medical Science,a tertiary care referral center in northern India.Here,we have included 37 consecutive patients with hydatid cysts of the liver and spleen.Diagnosis was made by laboratory and imaging findings(abdominal sonography or contrast enhanced CT scans).All patients were managed with laparoscopic partial pericystectomy.Intraoperatively,a betadine-soaked long ribbon gauze,high-pressure suction canula,and an endo-bag were used in all patients.The collected data included patient demography,location,size,and number of cysts,WHO type,operative time,blood loss,postoperative complications,hospital stay and follow-up.Result:In our series,the mean age was 38.4±13.6 years,15(40.5%)were men and 22(59.5%)were women.The right lobe of the liver was the most commonly affected site(21,56.8%).The mean operative time was 80.0±32.0 min,and intraoperative blood loss was 23.6±11.5 mL.Bile leak was present in 6(16.2%)patients.There was no mortality.The hospital stay was 5(3,9)days,and no recurrence was observed at a median follow-up of 36 months.Conclusion:Laparoscopic partial pericystectomy using this technique is safe in the management of hydatid cysts.Simply,proper packing and safe removal of soaked gauzes can minimize the incidence of postoperative complications and recurrence.

Hydatid Cyst of the Liver: About a Case at the Digestive and General Surgery Department of the University Hospital of Bouaké(Côte d’Ivoire)

Hydatid cyst of the liver (KHF) is a parasitic condition caused by the development of the larval form of the dog tapenia Echinococcus granulosus. In sub-Saharan Africa, few writings are interested in this pathology, which remains common and constitutes a public health problem in highly endemic countries [1] [2]. We report the observation of a 61-year-old hypertensive patient owner of a dog admitted for abdominal pain without abdominal mass. In whom ultrasound and computed tomography have made it possible to make the diagnosis of hydatid cyst of the liver (KHF). The patient underwent surgery. We performed an associated conservative treatment post-operative albendazole. The post-operative follow-up was simple. In our patient the evolution was good after a setback of more than 2 months. Through this observation and a review of the literature, we insist on the contribution of imaging in diagnosis and treatment, which is essentially surgical.

Fatal Rupture of a Giant Hydatid Cyst in an Elderly Patient

Hydatid cyst (HC) disease, which is endemic in Turkey, is mainly located in the liver. Cyst rupture is the most common complication of HC. Ultrasonography (US) and computerized tomography (CT) are the main diagnostic modalities for HC disease. Presented herein was a case of an elderly female patient who died shortly after presenting to the emergency department with severe abdominal pain. A giant HC was detected on initial evaluation by US. However, the presence of significant amounts of free fluid in the peritoneal space following a CT of the abdomen. The patient died despite medical and surgical intervention.

Predisposing factors and surgical outcome of complicated liver hydatid cysts

AIM: To evaluate the predisposing factors for peritoneal perforation and intrabiliary rupture and the effects of these complications on surgical outcome in liver hydatid disease.METHODS: A total of 372 patients with liver hydatid cysts who had undergone surgical treatment were evaluated retrospectively. Twenty eight patients with peritoneal perforation, 93 patients with spontaneous intrabiliary perforation, and 251 patients with noncomplicated hydatid cysts were treated in our clinics.RESULTS: When the predisposing factors for complications were evaluated, younger age, superf icial position, and larger cyst dimensions (P < 0.05; range, 0.0010.017) increased peritoneal perforation rates. It was shown that older age increased cyst dimensions, and presence of multiple and bilobar cysts increased intrabiliary rupture rates (P < 0.05; range, 0.0010.028). Partial pericystectomy and drainage was the most frequent surgical procedure in all groups (71.6%). The incidence of postoperative complications in the peritoneal perforated group, in the intrabiliary ruptured group, and in the noncomplicated group was 25%, 16.1% and 5.5%, respectively. When compared, complication rates were significantly different (P = 0.002). When length of hospital stay was compared, there was no signif icant difference between the groups (P > 0.05). The overall recurrence rate was 3.8% (14 patients), but there was not any statistical difference among the patient groups (P = 0.13). The early postoperative mortality rate was 1.1%. CONCLUSION: In peritoneally perforated and intrabiliary ruptured cases, the most important steps are irrigation of the peritoneal cavity and clearance of the cystic material from the biliary tree.

Conquering new battlegrounds:Successful management of isolated giant retrovesical hydatid cyst with robotic assistance

Hydatid disease(HD)is an accidental human parasitic infestation by cestodes and is most commonly caused by Echinococcus granulosus.Liver happens to be the most common site of involvement,although involvement of other organ symptoms is not uncommon.Involvement of the retrovesical pouch by hydatidosis is generally secondary in nature with an incidence of 0.1%-0.5%only.Primary retrovesical hydatid cyst(RVHC)is extremely rare with only few cases in existing literature.RVHC can present with a wide gamut of symptoms ranging from asymptomatic to obstructive uropathy.A 38-year-old male presented to us with complaints of lower urinary tract symptoms(LUTS)and was found to have an isolated primary retrovesical hydatid cyst on evaluation.The RVHC had compressed the right ureter leading to a grossly hydronephrotic non-functional right kidney.The patient was started on albendazole therapy and underwent robot assisted right nephroureterectomy and partial pericystectomy for the RVHC.The postoperative period was uneventful with resolution of symptoms.This report highlights the various clinical presentations of RVHC as well as the minimal invasive management of this rare entity.

Combined Hepatocardiac Hydatid Cystic Disease

Cardiac echinococcus is a serious problem. Although it is rare, it could cause dangerous complications like anaphylactic shock which could be fatal. In our case a 14-year-old female complained with the intermittent chest pain and had combined cystic lesions in the heart and the liver. The liver cyst was treated conservatively, while the heart cyst was excised by open heart surgery.

Hydatid Cyst of Para-Spinal Muscles as a Rare Cause of Back Pain in a Woman: A Case Report and Review of Literature

Introduction: Hydatid cyst formation is rare in organs such as muscle, bone and spine. Para-spinal involvement is an uncommon finding with a prevalence of less than 0.5% in the literatures. Presentation of Case: In the present paper, we reported a case of primary hydatid cyst in lumbar para-spinal area. The patient presented with complaint of chronic back pain and swelling in right thoracolumbar area. A suspicious mass was revealed in lumbar spine x-ray presenting as multi-loculated cystic mass on further evaluation by magnetic resonance imaging (MRI). The patient underwent surgery and the cyst was excised completely. Histopathological evaluations confirmed the hydatid disease. Discussion: Hydatid disease is a zoonotic infectious disease caused by Echinococcus granulosus. The parasitic cysts can form in any part of the host body. The liver and lungs are the most commonly involved organs. The occurrence of these lesions in certain areas such as para-spinal muscles is rare. The cystic mass is detected by radiologic modalities and is confirmed by pathologic examination. Surgery is the mainstay of treatment. Conclusion: Hydatid disease should be on differential diagnosis list facing a cystic lesion in any part of the body especially in the endemic areas. Moreover, radiologic and serologic assessments are important in confirming the diagnosis.

A Nonglycosylated 27 KDa Molecule as Common Antigen between Human Breast Cancer and Echinococcus granulosus Hydatid Cyst Wall

Background: Hydatid cyst, which has anti-cancer activities, is outwardly covered with the cyst wall. It is in close contact with the host tissues and its molecules presented to the immune system. In this work immunological reaction of the sera of breast cancer patients with the hydatid cyst wall antigens has been investigated. Method: For this purpose, sera of patients with breast cancer, hydatid cyst and normal human sera were collected and their reaction with hydatid cyst wall antigens was tested using western immunoblotting technique. Results: All sera of patients with breast cancer, hydatid cyst and also human normal sera reacted with a band in western immunoblotting. However, sera of patients with breast cancer showed reaction with a 27 KDa band. Results of this work also revealed that this band was not glycosylated and may express only in some stages of breast cancer development. Conclusion: Sera of patients with breast cancer cross reacted with a nonglycosylated antigen of hydatid cyst wall. However, more work is recommended to find if this band involves in anticancer activity of the hydatid cyst.

Review of the treatment of liver hydatid cysts

A review was carried out in Medline,LILACS and the Cochrane Library.Our database search strategy included the following terms: "hydatid cyst","liver","management","meta-analysis" and "randomized controlled trial".No language limits were used in the literature search.The latest electronic search date was the 7th of January 2014.Inclusion and exclusion criteria: all relevant studies on the assessment of therapeutic methods for hydatid cysts of the liver were considered for analysis.Information from editorials,letters to publishers,low quality review articles and studies done on animals were excluded from analysis.Additionally,well-structured abstracts from relevant articles were selected and accepted for analysis.Standardized forms were designed for data extraction; two investigators entered the data on patient demographics,methodology,recurrence of HC,mean cyst size and number of cysts per group.Four hundred and fourteen articles were identified using the previously described search strategy.After applying the inclusion and exclusion criteria detailed above,57 articles were selected for final analysis: one meta-analysis,9 randomized clinical trials,5 non-randomized comparative prospective studies,7 non-comparative prospective studies,and 34 retrospective studies(12 comparative and 22 noncomparative).Our results indicate that antihelminthic treatment alone is not the ideal treatment for liver hydatid cysts.More studies in the literature support the effectiveness of radical treatment compared with conservative treatment.Conservative surgery with omentoplasty is effective in preventing postoperative complications.A laparoscopic approach is safe in some situations.Percutaneous drainage with albendazole therapy is a safe and effective alternative treatment for hydatid cysts of the liver.Radical surgery with preand post-operative administration of albendazole is the best treatment option for liver hydatid cysts due to low recurrence and complication rates.

Imaging in pulmonary hydatid cysts

Hydatid disease is a zoonosis that can involve almost any organ in the human body. After the liver, the lungs are the most common site for hydatid disease in adults. Imaging plays a pivotal role in the diagnosis of the disease, as clinical features are often nonspecific. Classical radiological signs of pulmonary hydatid cysts have been described in the literature, aiding in the diagnosis of the disease. However, complicated hydatid cysts can prove to be a diagnostic challenge at times due to their atypical imaging features. Radiography is the initial imaging modality. Computed tomography can provide a specific diagnosis in complicated cases. Ultrasound is particularly useful in peripheral lung lesions. The role of magnetic resonance imaging largely remains unexplored.

Percutaneous aspiration and drainage with adjuvant medical therapy for treatment of hepatic hydatid cysts

AIM:To determine the efficacy and success of percutaneous aspiration irrigation and reaspiration(PAIR) in the management of hepatic hydatidosis.METHODS:Twenty-six patients with 32 hepatic hydatid cysts had PAIR.Twenty-two patients received at least 2 wk of drug therapy before the procedure was carried out to reduce the risk of recurrence from spillage during the procedure.The procedure was performed under local anesthesia with a 19-gauge 20 cm long needle,the cyst was punctured,cystic content(approximately 30 mL) was aspirated by a 12-14 F pigtail catheter and aspirated fluids were sent for analysis.Once the cyst was almost empty,two-thirds of the net amount of material aspirated was replaced by hypertonic saline and left in the cavity for about 30 min,with the catheter left in place for reaspiration of most of the fluid.When the amount of fluid drained was less than 10 mL per 24 h,the drainage catheter was removed.RESULTS:All 32 cysts showed evidence of immediate collapse after completion of the procedure,and before discharge from hospital,ultrasound examination showed fluid reaccumulation in all cysts.Serial follow-up showed a progressive decrease in the size and change in the appearance of cysts.To confirm the sterility of these cystic cavities,seven cysts were reaspirated on average 3 mo after the procedure.Investigations revealed no viable scolices.CONCLUSION:PAIR using hypertonic saline is very effective and safe with proper precautions.

Ruptured hydatid cyst in a patient with shock

Echinococcosis is a severe helminthic zoonosis largely caused by Echinococcus granulosus and frequently encountered in endemic areas.The liver and lung are the most frequently involved organs.Cyst rupture into the peritoneal cavity represents a rare but serious complication.Herein,we describe an acute occurrence of anaphylactic shock due to a spontaneous rupture of hydatid cyst in a 21-year-old Turkish patient unwittingly infected by Echinococcosis.Resection surgery of the perforated cyst in combination with cleaning of the abdominal cavity was performed.The patient rapidly improved and no relapse occurred during a follow-up of 8 months.Anaphylaxis is a serious complication of hydatid cyst rupture and needs to be promptly diagnosed.The main objective of our report is to underscore this life-threatening complication that should be considered when anaphylactic shock of unknown origin occurs,even in non-endemic regions.Moreover,we emphasize the need for a radical surgical approach to avoid widespread dissemination.

Pericyst: The outermost layer of hydatid cyst

Hydatid disease,caused by the parasite Echinococcus granulosus,mostly affects the liver and the lungs with hydatid cysts which consist of three layers:(1)the outer pericyst;(2)the middle laminated membrane;and(3)the inner germinal layer.Pericyst,as the outermost layer of the hydatid cyst,is made by host cells encasing the hydatid cyst.An extremely close interaction exists between this host tissue and the parasite,and any degenerative changes of the pericyst would result in hydatid cyst degeneration or rupture.The pericyst plays an undeniably important role in the development and survival of the hydatid cyst.

Coexistence of duodenum derived aggressive fibromatosis and paraduodenal hydatid cyst: A case report and review of literature

Intra-abdominal aggressive fibromatosis is a locally aggressive tumor mostly originating from the mesentery or retroperitoneal space, infiltrating adjacent tissues, and very rarely metastasizing to distant organs. There are only two case reports in the English language literature where intra-abdominal aggressive fibromatosis originated from the intestinal wall. In this study, we aimed to report a case of aggressive fibromatosis originating from the muscularis propria layer of the duodenum and invading pancreas. Another interesting aspect of this case is that a primary paraduodenal hydatid cyst was incidentally detected in the surgical specimen. A 46-year-old female patient presented to our clinic with postprandial nausea and vomiting. A contrast-enhanced abdominal computerized tomography revealed a mass lesion with a size of 100 mm × 80 mm which originated from the distal pancreas and compressed the gastric pilor externally. Upon exploration the distal part of duodenum, proximaljejunum, and pancreatic mass were noted to form a conglomerated structure. Therefore, the fourth part of the duodenum, a 25 cm part of the proximal jejunum, distal pancreas, and the spleen were excised enbloc. The pathology report of the specimen indicated fibromatosis with a diameter of 55 mm that originated from the muscularis propria of the duodenum and extended into the pancreatic parenchyma. There was also an incidentally detected 10 mm paraduodenal hydatid cyst. No tumor recurrence was detected at a follow-up period of 24 mo. In conclusion, the most ideal treatment of desmoid-type fibromatosis is surgical resection of the mass lesion with clean surgical borders. Although rare, this tumor may originate from the intestinal wall. Histopathological verification is of great significance for a proper diagnosis.

Hydatid cyst of the pancreas:Report of an undiagnosed case of pancreatic hydatid cyst and brief literature review

AIM: To overview the literature on pancreatic hydatid cyst(PHC) disease, a disease frequently misdiagnosed during preoperative radiologic investigation.METHODS: PubMed, Medline, Google Scholar, and Google databases were searched to identify articles related to PHC using the following keywords: hydatid cyst, hydatid disease, unusual location of hydatid cyst, hydatid cyst and pancreas, pancreatic hydatid cyst, and pancreatic echinococcosis. The search included let-ters to the editor, case reports, review articles, original articles, meeting presentations and abstracts that had been published between January 2010 and April 2014 without any restrictions on language, journal, or country. All articles identified and retrieved which contained adequate information on the study population(including patient age and sex) and disease and treatment related data(such as cyst size, cyst location, and clinical man-agement) were included in the study; articles with in-sufficient demographic and clinical data were excluded. In addition, we evaluated a case of a 48-year-old fe-male patient with PHC who was treated in our clinic.RESULTS: A total of 58 patients, including our one new case,(age range: 4 to 70 years, mean ± SD: 31.4 ± 15.9 years) were included in the analysis. Twenty-nine of the patients were female, and 29 were male. The information about cyst location was available from studies involving 54 patients and indicated the follow-ing distribution of locations: pancreatic head(n = 21), pancreatic tail(n = 18), pancreatic body and tail(n = 8), pancreatic body(n = 5), pancreatic head and body(n = 1), and pancreatic neck(n = 1). Extra-pancreatic locations of hydatid cysts were reported in the studies involving 44 of the patients. Among these, no other focus than pancreas was detected in 32 of the patients(isolated cases) while 12 of the patients had hydatid cysts in extra-pancreatic sites(liver: n = 6, liver + spleen + peritoneum: n = 2, kidney: n = 1, liver + kidney: n = 1, kidney + peritoneum: n = 1 and liver + lung: n = 1). Serological information was available in the studies involving 40 patients, and 21 of those pa-tients were serologically positive and 15 were serologi-cally negative; the remaining 4 patients underwent no serological testing. Information about pancreatic cyst size was available in the studies involving 42 patients; the smallest cyst diameter reported was 26 mm and the largest cyst diameter reported was 180 mm(mean ± SD: 71.3 ± 36.1 mm). Complications were avail-able in the studies of 16 patients and showed the fol-lowing distribution: cystobiliary fistula(n = 4), cysto-pancreatic fistula(n = 4), pancreatitis(n = 6), and portal hypertension(n = 2). Postoperative follow-up data were available in the studies involving 48 patients and postoperative recurrence data in the studies of 51 patients; no cases of recurrence occurred in any patient for an average follow-up duration of 22.5 ± 23.1(range: 2-120) mo. Only two cases were reported as having died on fourth(our new case) and fifteenth days respectively. CONCLUSION: PHC is a parasitic infestation that is rare but can cause serious pancreato-biliary complica-tions. Its preoperative diagnosis is challenging, as its radiologic findings are often mistaken for other cystic lesions of the pancreas.

Intraperitoneal rupture of the hydatid cyst: Four case reports and literature review

BACKGROUND Most patients with hydatid cysts are asymptomatic, and they are diagnosed incidentally during radiological evaluations performed for other reasons.However, some patients develop symptoms and complications due to cyst size,location, and the relationship between the cyst and adjacent structures. The most serious complications that can occur are rupture of the cysts into the biliary tract,vascular structures, hollow viscus, and peritoneal cavity. We aimed to describe the management of four cases of intraperitoneal rupture of hydatid cysts.CASE SUMMARIES Four patients aged between 27 and 44 years(two men and two women) were admitted to our clinic with sudden abdominal pain(n = 4), hypotension(n = 3),and anaphylaxis(n = 2). Three of the perforated cysts were located in the liver,and one was located in the spleen. Two patients developed cyst rupture after minor trauma, and the other two developed spontaneous rupture. Enzymelinked immunosorbent assay IgG results were positive for two patients and negative for the other two. All patients received albendazole treatment after surgical intervention(range: 2-6 mo). Two patients developed hepatic abscesses requiring drainage; one of these patients also developed hydatid cyst recurrence during postoperative follow-up(range: 25-80 mo).CONCLUSION Intraperitoneal rupture is a life-threatening complication of hydatid cysts. It is important to manage patients with surgical intervention as soon as possible with aggressive medical treatment for anaphylactic reactions.

Sumac (<i>Rhus coriaria</i>L.): Scolicidal Activity on Hydatid Cyst Protoscolices

Background: Few anthelmintics are available for the treatment of hydatid disease caused by the parasite Echinococcus granulosus. The appearance of resistance to synthetic anthelmintics and the adverse side effects of chemical drugs, stimulated the research of alternatives, such as medicinal plants. In the present study, the scolicidal effect of methanolic extract of sumac (Rhus coriaria) was investigated. Methods: Protoscolices were aseptically collected from sheep livers containing hydatid cysts. Three concentrations of sumac extract (10, 30 and 50 mg/mL) were used for 10, 20 and 30 min. Viability of protoscolices was confirmed by 0.1% eosin staining. Results: While the rate of dead protoscolices was 16.93% in the ontrol group, when protoscolices were exposed to sumac extract at the concentration of 10 mg/mL , the rate of dead protoscolices increased to 94.13%, 97.67% and 100% after 10, 20 and 30 minutes, respectively. The mortality rate of protoscolices increased to 98.89%, and 100% when they were exposed to 30 mg/mL concentration of sumac extract for 10 and 20 minutes respectively. One hundred percent mortality rate was observed at concentration of 50 mg/mL after 10 min of exposure. Conclusions: This in vitro study showed that methanolic extract of R.coriaria may be considered as an effective natural scolicidal agent.

The Role of Endoscopic Retrograde Cholangiopancreatography (ERCP) in the Management of Intra-Biliary Rupture of Liver Hydatid Cysts (IBRH): Follow-Up of 12 Cases

Background: Intra-biliary rupture of hydatid cyst [IBRH] is not a rare complication of hydatid disease of the liver and surgery until recently is the only definitive treatment. With the introduction of ERCP preoperatively or postoperatively there was a great reduction in the operative complications. There were reports in which the ERCP was the sole treatment of this condition. Objective: To evaluate role of ERCP in the management of cases of IBRH. Design: A retrospective study of 7 cases of IBRH and prospective study of 5 cases of IBRH managed by ERCP. Setting: The ERCP Unit of Kurditan Center for Gastroenterology & Hepatology, Asulaimaneyah-Iraqi, Kurdistan, Iraq. Main Outcome Measurements: Improvement in the symptoms, obstructive liver functions pattern and ultrasonic findings in these patients following ERCP management. Methods: This is a study of 12 cases of IBRH managed by ERCP in the Kurdistan Center of Gastroenterology (KCGE) in Asulaimaneyah-Iraq, from 2007-2010. Seven cases of these were studied retrospectively from the available information on the center computers and on follow-up of these patients, while the other five patients were studied prospectively during the study period. We collected the available information: laboratory investigations, trans-abdominal ultrasonography (TAUS), computed tomography (CT) or magnetic resonance images (when available), before and after ERCP. We depended on the liver functions, trans-abdominal ultrasound and the clinical presentation before and after the ERCP;some patients were contacted via mobile phone for follow-up. Results: Cases were more males than females (58% vs 42%);most were from the ages between 30 - 50 years. The clinical presentation was fever, jaundice, itching and right hypochondrial pain in most patients. The liver function tests were obstructive pattern with elevated direct bilirubin and alkhaline phosphates in most patients. The trans-abdominal ultrasound revealed dilated common bile duct and single liver cyst in most patients and 2 or 3 cysts in others. The ERCP management led to improvement in clinical, laboratory and ultrasonic findings in 6 patients and in these 6 patients ERCP was the only procedure needed and proved by follow-up of these patients for 1 year in 4 patients and 2 years in the other 2 patients, especially in those with hydatid mebranes seen at ERCP and those with cholangiographic evidence of communication with the cyst;surgery was needed in 5 cases and one patient died from septic shock. Conclusions: ERCP is an important management strategy for patients with IBRH, which can lead to clinical, laboratory and ultrasonographic improvements, and can be the only required procedure in more than 50% of cases especially in those with hydatid mebranes seen at ERCP and those with cholangiographic evidence of communication with the cyst.
