For these patients a cesarean section can be life threatening due to uncontrolled massive hemorrhage. Prevention and control of massive blood loss utilizing a multidisciplinary approach can be lifesaving. We present a case report of a 33 years old pregnant woman at 35 weeks of gestation diagnosed with an extensive uterine arteriovenous malformation and innumerable tortuous vessels who was scheduled for a cesarean section. Her previous vaginal delivery was complicated by significant bleeding requiring uterine artery embolization. Pre-operative prophylactic aortic and right iliac artery balloon occlusion catheters were placed under monitored anesthesia care. The extracorporeal life support team was available to initiate veno-venous or arteriovenous bypass. Cesarean section was performed with careful identification of the uterine vessels under ultrasound guidance and ultimately the bleeding was well controlled. Postoperatively, the patient underwent uterine artery embolization. It is our strong belief that although we did not face a major disaster during this cesarean section, our comprehensive plan and multi-disciplinary approach were essential to ensuring the safety of the parturient and newborn. 展开更多

Cerebral cavernous malformations are a rare and congenital vascular malformation that can present as a challenge in neurosurgical management. The term “giant cerebral cavernous malformations” still does not have a clear definition in the literature, with a wide variety of results. It is known, however, that there is an association between the size of the cavernoma and postoperative sequelae, especially in those with a size greater than 3 cm in its largest diameter. We present a case report of resection of a giant brain cavernoma measuring approximately 8 cm in its largest diameter, emphasizing on clinical presentation, diagnoses and postoperative evolution. Additionally, we performed a comprehensive review of the existing literature on the subject, addressing the epidemiology, pathophysiology, diagnostic methods, treatment options, and prognosis associated with this condition. 展开更多

These structures are likely to be affected in Chiari malformation. Therefore, SEP abnormalities may provide valuable information in patients with CM. However, the consistency of SEP abnormality or normality with the damage is a matter of research. Knowing whether median nerve somatosensory evoked potential (SEP) is useful in revealing subclinical damage in patients with Chiari malformation is important in the treatment and follow-up plan of the disease. The aim of this study was to investigate the relationship between median nerve SEP values and the severity of cerebellar ectopia in patients with Chiari type 1 malformation. Median nerve SEP values were obtained from 30 healthy individuals and 146 individuals with Chiari malformation. The cerebellar ectopia degree and McRae line length were measured. SEP values were not significantly different between groups. The McRae line was found to be significantly shorter in the control group than in the Chiari malformation group (p = 0.031). There was no correlation between the degree of cerebellar ectopia and the length of the McRae line (r = 0.002, p = 0.979). Neither cerebellar ectopy degree nor McRae line length had a relationship with SEP values (r = -0.153, p = 0.066;r = -0.056, p = 0.500, respectively). There was no difference in cerebellar ectopy degree or SEP values between the groups with cerebellar ectopy with and without a syrinx (p = 0.899;p = 0.080, respectively). Likewise, McRae line length was not found to be related to the presence of a syrinx (p = 0.139). Median nerve SEP examination was not beneficial for diagnosing asymptomatic-oligosymptomatic Chiari malformation as a subclinical injury, whether accompanied by syringomyelia or not. 展开更多

It is associated with other births defects like cardiac malformations. Descriptions in Sub Saharan Africa are rare, justifying the present report. Case Report: We reported the cases of 3 female patients, diagnosed with hypothyroidism, presenting in addition pulmonary stenosis. The diagnosis was late in all the patients and we noticed clinical improvement under levothyroxine. Conclusion: Association congenital hypothyroidism and cardiac defect is not rare. Our patients are female with no history of consanguinity, presenting congenital hypothyroidism with a gland in situ associated with pulmonary stenosis. Systematic screening of other births defects is thus recommended in affected patients. 展开更多

In this study, we present a representative case of multiple glomuvenous malformation in a 12-year-old female patient. Approximately five years ago, the patient developed multiple blue-purple papules and plaques on her hypogastrium and right thigh, which progressively enlarged and presented tenderness. Histopathological examination confirmed the diagnosis of glomuvenous malformation. Following two injections of lauromacrogol, a significant improvement was observed in the lesions, including a resolution of tenderness. These findings suggest that sclerotherapy not only exhibits evident therapeutic efficacy but also effectively alleviates pain while addressing both aesthetic and therapeutic concerns. 展开更多

BACKGROUND Vascular malformations(VMs)arise as a result of errors in the process of angiogenesis and are usually present at birth,but may not become apparent until after birth.However,giant VMs of the head and face are uncommon,with few reported cases,and the prognosis for their surgical intervention is unclear.CASE SUMMARY A 12-year-old girl was admitted to the hospital with findings of an enlarged right temporal scalp.After admission,computed tomography(CT)angiography of cerebral ateries showed a right occlusal gap and a right temporal artery venous malformation.Furthermore,cerebral angiography showed a right temporal lobe VM with multiple vessels supplying blood.The patient underwent surgery to remove the malformed vessels and the eroded skull.Two hours after the surgery,the patient's right pupil was dilated,and an urgent CT scan of the skull showed a right subdural haematoma under the incision,which was urgently removed by a second operation.After surgery,we gave continuous antibiotic anti-infection treatment,and the patient recovered well and was discharged two weeks later.CONCLUSION Surgical removal of giant haemangiomas is risky and adequate preoperative(including interventional embolisation)and intraoperative preparations should be made. 展开更多

BACKGROUND Acute lower gastrointestinal bleeding(LGIB)is a common occurrence in clinical practice.However,appendiceal bleeding is an extremely rare condition that can easily be overlooked and misdiagnosed.The preoperative detection of appen-diceal bleeding often poses challenges due to the lack of related guidelines and consensus,resulting in controversial treatment approaches.CASE SUMMARY We presented a case of a 33-year-old female who complained of hematochezia that had lasted for 1 d.Colonoscopy revealed continuous bleeding in the appen-diceal orifice.A laparoscopic appendectomy was performed immediately,and a pulsating blood vessel was observed in the mesangium of the appendix,accor-dingly,active bleeding into the appendicular lumen was considered.Pathological examination revealed numerous hyperplastic vessels in the appendiceal mucosa and dilated capillary vessels.CONCLUSION The preoperative detection of appendiceal bleeding is often challenging,colo-noscopy is extremely important,bowel preparation is not routinely recommend-ed for patients with acute LGIB or only low-dose bowel preparation is recom-mended.Laparoscopic appendectomy is the most appropriate treatment for appendiceal bleeding. 展开更多

BACKGROUND The rare co-occurrence of oligodendroglioma and arteriovenous malformation(AVM)in the same intracranial location.CASE SUMMARY In a 61-year-old man presenting with progressive headaches,is described in this case study.Preoperative multimodal imaging techniques(computed tomography,magnetic resonance imaging,magnetic resonance spectroscopy,digital subtraction angiography,and computed tomography angiography)were employed to detect hemorrhage,cystic and solid lesions,and arteriovenous shunting in the right temporal lobe.The patient underwent right temporal craniotomy for lesion removal,and postoperative pathological analysis confirmed the presence of oligodendroglioma(World Health Organization grade II,not otherwise specified)and AVM.CONCLUSION The preoperative utilization of multimodal imaging examination can help clinicians reduce the likelihood of misdiagnosis or oversight of these conditions,and provides important information for subsequent treatment.This case supports the feasibility of craniotomy for the removal of glioma with AVM. 展开更多

BACKGROUND Digital subtraction angiography(DSA),the gold standard for the diagnosis of intracranial arteriovenous malformations(AVMs),can show clean nidus resection,leading to a perceived cure.Most cases of intracranial AVM recurrence have been reported in pediatric patients.The conventional understanding indicates that AVMs arise when abnormal blood vessels develop between the fourth and eighth weeks of embryonic development,which coincides with the typical period of blood vessel formation in the brain.As such,recurrent ectopic AVM are rare in adults.CASE SUMMARY Herein,we present the case of a 31-year-old adult with a history of an intracranial AVM originally diagnosed with a symptomatic de novo cerebellar AVM formation.Recurrence was observed five years following angiographically-confirmed excision of the initial AVM.DSA performed prior to initial AVM resection indicated no cerebellar abnormalities.Moreover,the recurrent arteries exhibited differences in arteries and draining veins.In addition to reporting this case,we analyzed six previously-reported adult patients with similar ectopic recurrent AVMs.These cases are summarized to review and explore the potential causes of ectopic AVM recurrence in adults,which increase the likelihood of acquired AVM.CONCLUSION The clinical course of the reported patients demonstrated the possibility of ectopic AVM recurrence in adults.The median time between the diagnosis of the initial AVM and the occurrence of ectopic recurrent AVM in adults was 11 years(range:5–20 years).Magnetic resonance imaging follow-up for more than 10 years may be required in adult AVM-treated patients. 展开更多

Objective:To investigate the computed tomography(CT)and magnetic resonance imaging(MRI)features of cavernous hemangioma malformation(CHM)to enhance diagnostic accuracy.Methods:The CT and MRI findings and clinical information of 23 patients with CHM were retrospectively analyzed.Results:CT examinations were conducted in 7 cases,while MRI was utilized in 23 cases.Additionally,SWI was employed in 5 cases and enhanced imaging techniques were applied in 14 cases.Among the observed lesions,20 cases presented with a singular lesion,whereas 3 cases exhibited multiple lesions.The lesions were located in 8 frontal lobes,6 cerebellums,2 brainstems,6 temporal lobes,1 basal ganglia,3 parieto-occipital lobes,and 2 thalamus regions.The nodules appeared as quasi-circular lesions with clear or well-defined boundaries.They presented as isodense lesions on CT scans,with one lesion showing peritumoral edema.On MRI,T1-weighted imaging(T1WI)demonstrated isointense signals,while T2-weighted imaging(T2WI)showed isointense and hyperintense signals.Additionally,10 lesions exhibited a low signal ring on T2WI.Diffusion-weighted imaging(DWI)revealed nodular or isointense low signals,while susceptibility-weighted imaging(SWI)displayed enlarged areas of low signal.Fourteen lesions underwent contrast-enhanced scanning,with 2 lesions showing no obvious enhancement,1 lesion demonstrating mild to moderate enhancement,and 11 lesions exhibiting significant enhancement.Notably,6 of these enhanced lesions were surrounded by small blood vessels.Conclusion:Cavernous hemangioma malformation is more commonly found in individual cases.CT alone lacks specificity,making it prone to misdiagnosis.A more comprehensive evaluation of cavernous hemangioma malformation can be achieved through a combination of MRI,DWI,SWI,and enhanced examination,providing valuable references for clinical assessment. 展开更多

Based on the latest classification by the International Society for the Study of Vascular Anomalies in 2018,vascular malformations(VMs)can be categorized into simple,combined,VMs of major named vessels,and VMs associated with other anomalies.Simple VMs include lymphatic,venous,capillary,and arteriovenous malformations(AVMs).AVMs represent disorders of direct arteriovenous shunts caused by the absence of a capillary bed between the involved arteries and veins.This abnormal vascular communication causes arterial blood to accumulate in the venous vessels,thus resulting in venous hypertension and characteristic clinical manifestations,such as pulsation,tremors,and elevated temperature.AVMs can occur sporadically or as manifestations of syndromic lesions and are considered among the most complex and challenging VMs.The diagnosis and treatment of AVMs can vary depending on the lesion location and associated clinical symptoms,thus complicating their management.Herein,we discuss peripheral AVMs in terms of their clinical manifestations,imaging examinations,and staging systems to provide a comprehensive reference for the treatment,evaluation methods,and follow-up procedures for this vascular anomaly. 展开更多

As three-dimensional“organ-like”aggregates,human cortical organoids have emerged as powerful models for studying human brain evolution and brain disorders with unique advantages of humanspecificity,fidelity and manipulation.Human cortical organoids derived from human pluripotent stem cells can elaborately replicate many of the key properties of human cortical development at the molecular,cellular,structural,and functional levels,including the anatomy,functional neural network,and interaction among different brain regions,thus facilitating the discovery of brain development and evolution.In addition to studying the neuro-electrophysiological features of brain cortex development,human cortical organoids have been widely used to mimic the pathophysiological features of cortical-related disease,especially in mimicking malformations of cortical development,thus revealing pathological mechanism and identifying effective drugs.In this review,we provide an overview of the generation of human cortical organoids and the properties of recapitulated cortical development and further outline their applications in modeling malformations of cortical development including pathological phenotype,underlying mechanisms and rescue strategies. 展开更多

BACKGROUND Abernethy malformation is a rare congenital vascular malformation with a portosystemic shunt that may clinically manifest as cholestasis,dyspnea,or hepatic encephalopathy,among other conditions.Early diagnosis and classification are very important to further guide treatment.Typically,patients with congenital portosystemic shunts have no characteristics of portal hypertension.Herein,we report an 18-year-old female with prominent portal hypertension that manifested mainly as rupture and bleeding of esophageal varices.Imaging showed a thin main portal vein,no portal vein branches in the liver,and bleeding of the esophageal and gastric varices caused by the collateral circulation upwards from the proximal main portal vein.Patients with Abernethy malformation type I are usually treated with liver transplantation,and patients with type II are treated with shunt occlusion,surgery,or transcatheter coiling.Our patient was treated with endoscopic surgery combined with drug therapy and had no portal hypertension and good hepatic function for 24 mo of follow-up.CASE SUMMARY This case report describes our experience in the diagnosis and treatment of an 18-year-old female with Abernethy malformation type IIC and portal hypertension.This condition was initially diagnosed as cirrhosis combined with portal hypertension.The patient was ultimately diagnosed using liver histology and subsequent imaging,and the treatment was highly effective.To publish this case report,written informed consent was obtained from the patient,including the attached imaging data.CONCLUSION Abernethy malformation type IIC may develop portal hypertension,and traditional nonselective beta-blockers combined with endoscopic treatment can achieve high efficacy. 展开更多

BACKGROUND Brain arteriovenous malformations(bAVMs)remains one of the most prevalent causes of intracranial hemorrhage and stroke-like syndromes in the young adult population.Although it has been agreed upon that definitive treatment using either single or multi-modal approach is warranted for successful bAVM management,much debate still revolves regarding the optimal timing of definitive treatment.CASE SUMMARY In this report,we present a case of delayed,definitive endovascular treatment for ruptured bAVM in a 21-year-old female,3 mo post-ictus.The bAVM,with a left pericallosal feeding artery and cortical draining veins,was successfully obliterated through embolization using the Onyx 18.On follow-up the patient has recommenced her daily activities and experiences only mild occasional headaches with mild motor deficits.The report leads to our review on an important issue regarding the optimal timing of ruptured bAVM definitive management and bring forward the current evidence available on delayed vs immediate definitive bAVM intervention.We also highlight current issues that need to be addressed for clearer guidelines on definitive therapy initiation.CONCLUSION Current treatment paradigms of ruptured bAVM remains elusive,with substantial heterogeneity in the current literature.A consensus on the definition of“acute”vs“delayed”,management goal,follow-up length and outcome parameters are required to support formation of a clear paradigm. 展开更多

Malignant mesenchymal tumors (MTM) in children represent 5% to 10% of malignant tumors in children. They constitute a heterogeneous group of tumors of various differentiations depending on their supposed tissue of origin. They mainly include tumors of muscular origin, those derived from connective, vascular, nervous, or adipose tissue. Rhabdomyosarcoma (RMS) is the most common mesenchymal tumor in children and adolescents (60% to 70% of them). And it accounts for 5.8% of all malignant solid tumors in children. Almost half of rhabdomyosarcomas occur in the head and neck. The prognosis for this type of tumor is particularly poor. A case of rhabdomyosarcoma in the mandible with extension to the abdominal wall and unilateral testis in a 6-month-old infant is reported with evolution since birth. It is a purplish lesion at the level under the right chin which was initially taken for vascular malformation, evolving very quickly towards a mandibular mass deforming the painful face with inflammatory signs, followed by the appearance of a hard swelling under the skin on the left flank taking on the same aspect of the mandibular mass. This observation illustrates the need to know how to systematically think about tumor causes in the face of atypical aspects and to carry out an anatomopathological examination. 展开更多

Split hand/foot malformation (SHFM), formerly known as ectrodactyly is a rare congénital anomaly, its incidence varies from 1/8.500 to 1/25.000 live birth. It mainly affects the development of the limbs, its clinical variability is standard, can present as an isolated feature or as a syndrome associated with other congenital anomalies. Our objective was to present the two cases of SHFM, and to review the literature on the clinical aspects and discuss a probable origin. The father went to school and is a driver because the malformations concerned only the fingers, were less severe, and did not prevent the realization of certain simple gestures of the daily life. On the other hand, the malformations of the fingers of the newborn were severe and the absence of the thumbs compromised the later prehension function. Also the association of a microglossia and a cleft palate contributed to a weight loss that justified hospitalization. The clinical presentation of split hands and feet is variable and the prognosis depends on the type of anomaly. Familial cases suggest a probable genetic origin. Genetic testing is necessary to establish genetic counseling. 展开更多

Introduction: A congenital malformation is defined as a morphological abnormality of an organ or body region resulting from an abnormal developmental process during the formation of the embryo or fetus. Depending on their type, location and size, malformations can cause functional, psychological and aesthetic defects. The aim of this study is to document the frequency of congenital malformations, describe the characteristics of malformed newborns and their biological mothers, and identify the different types of malformations presented by newborns at the INSE. Methods: Descriptive cross-sectional study of clinically visible malformed newborns. It was carried out from January 1, 2021 to January 1, 2022 at the INSE neonatology unit. Epi info version 3.1 software was used for data entry and analysis. Results: Of a total of 2332 neonates hospitalized during the study period, 81 (3.5%) cases had at least one clinically visible congenital malformation. Nearly 84% had an age ≤ 7 days at the time of admission. The male sex was most concerned (60.5%). Newborns referred by a health facility accounted for 84%. Malformations of the digestive system accounted for 30.9% of cases, followed by those of the limbs (19.8%) and poly malformative syndrome (19.8%). Conclusion: This study shows that congenital malformations exist and are frequent in Guinea. Our results could therefore be the starting point for the future establishment of a national register of congenital malformations. 展开更多
