Many ganglioneuroma cases are detected incidentally unless they are large enough to cause compressive symptoms. We report an 18-year-old patient with posterior mediastinal ganglioneuroma which was abutting the descending aorta. The patient underwent successful resection by thoracoscopic approach and was followed up for one year with no complications. In summary, a detailed review with experts in both radiology and pathology is mandated to diagnose these tumors. Informed consent was obtained from the patient.展开更多

GNs are usually hormonally silent and tend to be discovered incidentally on imaging tests. Adrenalectomy is the gold standard for the treatment of primary adrenal GNs. Nevertheless,preoperative differential diagnosis of GNs remains extremely challenging,and thus histopathological examination is required in order to confirm the diagnosis of GN. Overall,prognosis after surgical resection seems to be excellent,without any recurrences or need for adjuvant therapy.展开更多

The most frequently involved sites are the posterior mediastinum, the abdominal cavity, and the retroperitoneal space. It rarely occurs in the cervical area, compressing the spinal cord. Neurofibromatosis type 1(NF-1) is an autosomal dominant inheritance disorder, whose prevalence rate approximates one per 3000.CASE SUMMARY We report an extremely rare case of bilateral and symmetric dumbbell GNs of the cervical spine with NF-1. A 27-year-old man with NF-1 presented with a one-year history of gradually progressive right upper extremity weakness and numbness in both hands. Magnetic resonance imaging showed bilateral and symmetric dumbbell lesions at the C1-C2 levels compressing the spinal cord. We performed total resection of bilateral tumors, and the postoperative histopathological diagnosis of the resected mass was GN. After operation, the preoperative symptoms were gradually relieved without complications. To our knowledge,this is the sixth report of cervical bilateral dumbbell GNs.CONCLUSION In some cases, cervical bilateral dumbbell GNs could be associated with NF-1.The exact diagnosis cannot be obtained before operation, and pathological outcome is the current gold standard. Surgical resection is the most effective option, and disease outcome is generally good after treatment.展开更多

The postoperative course was uneventful.The definitive diagnosis was ganglioneuroma.Immunocytochemistry showed positive staining with vimentin,S-100 protein, neurofilament and neuron-specific enolase.Ganglioneuroma is a rare benign tumor that can also present as a pancreatic tumor.Uncinatectomy is feasible,safe and a good surgical technique for the treatment of nonmalignant tumors located in the uncinate process of the pancreas.展开更多

They are abdominal masses growing slowly and differential diagnoses have to be considered. Surgical resection is important for definitive diagnosis because it represents the only therapeutic choice. Because of the benign nature of ganglioneuroma, adjuvant chemoor radiotherapy is not indicated but regular follow-up is necessary for an early diagnosis of potential local recurrence. We report a case of a 64-year-old man with a presacral ganglioneuroma.展开更多

Given the rarity of these tumors and their often close proximity to major vessels, there is a paucity of reports in the literature of minimally invasive resections of ganglioneuromas near the celiac plexus. We report a case of laparoscopic resection of a retroperitoneal ganglioneuroma adhering to the portal vein and celiac axis.CASE SUMMARY A 27-year-old female was referred to our medical center with a symptomatic retroperitoneal mass. Using high quality preoperative imaging and biopsies, we confirmed the diagnosis of a 4 cm ganglioneuroma abutting the celiac axis, portal vein, and the caudate lobe of the liver. We elected for laparoscopic resection after careful preoperative planning and discussions with the patient. Laparoscopy enhanced visualization of the tumor and its relationships to surrounding vital structures for optimal dissection. Ultrasonic energy devices and adjusting liver retraction to allow for manipulation of the mass facilitated a safe and effective resection in a tight space. There were no operative complications and the patient was discharged home on postoperative day 1 with no residual symptoms upon follow-up. With sufficient experience in laparoscopic surgery and preoperative imaging and diagnostics, a minimally invasive approach for removing this celiac plexus ganglioneuroma was successful.CONCLUSION In carefully selected patients, laparoscopic ganglioneuroma resection is appropriate, reducing postoperative morbidity, hospital length of stay, and recovery time.展开更多

The purpose of this study was to investigate correlation between contrast enhancement on CT and MRI and histological findings in posterior mediastinal ganglioneuromas. Materials and Methods: Contrast-enhanced (CE) CT (n = 11) and CE MRI (n = 5) of 12 patients with ganglioneuroma were reviewed. The attenuation, signal intensity, and dynamic enhancement pattern of the tumors were evaluated. The vascularity was histologically evaluated by the numbers of vessels. Results: Enhancement on CE-CT was none, mild, moderate, and high enhancement in 5 (45%), 2 (18%), 3 (27%), and 1 (9%) of the 11 lesions, respectively. Dynamic MRI showed mild, moderate and high enhancement in 3 (60%), 1 (20%) and 1 (20%) cases, respectively. The level of contrast enhancement correlated well only with the number of capillary vessels (r = 0.79, P = 0.0037). Conclusion: The posterior mediastinal ganglioneuromas sometimes show insufficient enhancement particularly on CE-CT. The level of enhancement might correlate with the amount of capillary vessels.展开更多

They are often asymptomatic. However, in rare cases, they may secrete catecholamines, vasoactive intestinal polypeptides (VIP), or androgenic hormones and manifest with flushing, symptoms of catecholamine excess or chronic diarrhea. We report a young Saudi girl with chronic secretory diarrhea, severe hypokalemia and abdominal distension. After an extensive work up, a well-defined hypodense heterogeneous mediastinal mass was noted in radio imaging. A complete recovery was seen after surgical removal of that mediastinal mass which turned to be a ganglioneuroma.展开更多

Currently, very limited literature is available to allow a differential diagnosis of these two conditions from each other. This study aimed to evaluate the clinical profile, differential diagnosis and surgical treatments of both conditions. Methods Clinical characteristics of 36 patients with adrenal pheocheomocytoma and 18 patients with adrenal ganglioneuroma were analyzed. Data from CT scans and surgical treatments from 1999 to 2007 were collected. Endocrine hormone tests and ^131I-metaiodobenzylguanidine （MIBG） were performed. Neither ^131I-MIBG nor endocrine hormone tests were available in 9 cases of asymptomatic adrenal ganglioneuroma with tumor size less than 4 cm and there were negative findings from contrast enhanced CT scans. The level of urine catecholamine of patients was compared by one-way analysis of variance. Results The mean age of patients in the adrenal ganglioneuroma group was 41.2 years （16-67 year） and in the adrenal pheochromocytoma patients 38 years （17-74 year）. Contrast enhanced CT showed that the foci were intensified in 5 cases （27.8%） of adrenal ganglioneuroma and there were obvious contrast indications in 30 （83.3%） of the pheochromocytoma. Catecholamine levels in a 24-hour urine sample were normal in 4 patients with adrenal ganglioneuroma and increased in 36 （100%） cases with adrenal pheochromocytoma. ^131I-MIBG nuclear scan showed negative results in 4 patients （100%） with adrenal ganglioneuroma and positive results in 25 （96.2%） with adrenal pheochromocytom. Laparoscopy for adrenal tumors was performed through a transperitoneal or retroperitoneal approach during a follow-up period of （43±6） months, and all cases survived well. Conclusions CT, urinary catecholamine and ^131I-MIBG are standard and efficient tools for differential diagnosis of adrenal ganglioneuroma from pheochromocytoma. Laparoscopic surgery can be performed through a transperitoneal or retroperitoneal approach depending on the finding of CT scans. Open surgery is necessary for patients with blood loss of more than 800 ml and violent fluctuation of intraoperative blood pressure.展开更多

In this report, we reviewed and summarized the clinical features,treatment, and prognosis of a posterior mediastinal ganglioneuroma. Case: Here, we report on a 29-year-old man referred to us with transient pain in the right side of the chest, lasting for three days. Physical examination revealed no abnormalities.The results of routine laboratory tests were within the normal ranges. Thoracic spinal magnetic resonance imaging showed a well-defined, solid mass in the right paravertebral region at the T5-T8 level, measuring 7.5 cm × 4.2 cm × 1.5 cm. To accurately locate the lesion during surgery, O-arm intraoperative imaging was used in conjunction with the Stealth Station navigation system. The tumor was completely excised and no related complications occurred. The tumor was an encapsulated mass with a solid, homogenous, grayish-tan cut surface. Histopathological examinations confirmed that the mass was a ganglioneuroma. Conclusions: Ganglioneuroma is a rare, benign tumor. Prior to treatment, a careful imaging evaluation is necessary in order to obtain an accurate diagnosis. A definitive diagnosis can be made by histological examination. En bloc resection is the preferred treatment for ganglioneuroma as it has an excellent prognosis.展开更多
文摘Ganglioneuroma is an extremely rare tumor that is derived from neural crest. Many ganglioneuroma cases are detected incidentally unless they are large enough to cause compressive symptoms. We report an 18-year-old patient with posterior mediastinal ganglioneuroma which was abutting the descending aorta. The patient underwent successful resection by thoracoscopic approach and was followed up for one year with no complications. In summary, a detailed review with experts in both radiology and pathology is mandated to diagnose these tumors. Informed consent was obtained from the patient.

文摘Background;Ganglioneuroma is a rare benign tumor,which is usually located in the posterior mediastinum and retroperitoneum.Occasionally,it involves the paraspinal region with intraspinal extension and becomes dumbbell shaped.Dumbbell ganglioneuromas rarely affect the lumbar spine,and only nine cases of dumbbell lumbar ganglioneuromas have been reported previously.Case presentation;We are reporting an extremely rare case of a giant dumbbell tumor in the lumbar spine.We performed a one stage total resection of the tumor with posterior approach and long-segment fixation and fusion.This approach is different from previous methods.Histopathological examination of the surgical specimen confirmed the diagnosis of ganglioneuroma.Thirty months follow up showed a satisfactory outcome.Conclusions:Single-stage posterior tumor resection with fixation and fusion is effective and an appropriate choice for the treatments of lumbar dumbbell ganglioneuromas.

文摘Objectives: Ganglioneuroma is a rare, benign neurogenic tumor arising from the sympathetic ganglia. In this report, we reviewed and summarized the clinical features,treatment, and prognosis of a posterior mediastinal ganglioneuroma. Case: Here, we report on a 29-year-old man referred to us with transient pain in the right side of the chest, lasting for three days. Physical examination revealed no abnormalities.The results of routine laboratory tests were within the normal ranges. Thoracic spinal magnetic resonance imaging showed a well-defined, solid mass in the right paravertebral region at the T5-T8 level, measuring 7.5 cm × 4.2 cm × 1.5 cm. To accurately locate the lesion during surgery, O-arm intraoperative imaging was used in conjunction with the Stealth Station navigation system. The tumor was completely excised and no related complications occurred. The tumor was an encapsulated mass with a solid, homogenous, grayish-tan cut surface. Histopathological examinations confirmed that the mass was a ganglioneuroma. Conclusions: Ganglioneuroma is a rare, benign tumor. Prior to treatment, a careful imaging evaluation is necessary in order to obtain an accurate diagnosis. A definitive diagnosis can be made by histological examination. En bloc resection is the preferred treatment for ganglioneuroma as it has an excellent prognosis.
