چکیده

Ganglioneuroma is an infrequent tumor composed of sympathetic ganglion cells and sheathed neurites. It arises mainly from the large sympathetic chains, most frequently in the posterior mediastinum and retroperitoneum, but rarely may develop from the peripheral sympathetic chains. It is usually benign, and may grow asymptomatically to relatively large size. However, it can cause symptoms due to local expansion and pressure on adjacent structures. It does not seem to have hormonal activity. Some ganglioneuromas contain immature cells or elements of neuroblastoma or pheochromacytoma and can metastasize. The preoperative diagnosis of retroperitoneal tumors has now become more frequent due to the extensive use of imaging modalities, mainly computed axial tomography. Whenever the imaging correlates with the clinical presentation, or there is a reasonable suspicion of a malignancy, operation is indicated. Many retroperitoneal space-occupying lesions are found in asymptomatic patients during attempts to diagnose other diseases. In these cases opinions differ as to therapeutic approach. Many adrenal tumors may be benign adenomas, and several therapeutic protocols have been proposed. The clinician can decide on the basis of clinical presentation and radiographic features whether a conservative approach rather than operation is indicated. Since the majority of retroperitoneal tumors are malignant, histologic diagnosis is essential and in such cases surgical intervention is warranted. A young patient with a retroperitoneal ganglioneuroma is presented.

A case of retroperitoneal ganglioneuroma.

We describe a rare case of a primary retroperitoneal ganglioneuroma that was found accidentally during preoperative examinations conducted due to a suspicion of ovarian cancer. Computerized tomography was not able to differentiate the retroperitoneal mass from an adrenal tumor. We diagnosed the retroperitoneal tumor by means of selective adrenal angiography.

Laparoscopic Excision of a Retroperitoneal Ganglioneuroma

OBJECTIVE Ganglioneuromas are rare benign tumors originating from ganglion cells. Ganglioneuromas are detected incidentally because they are asymptomatic. We report a case of laparoscopic excision of a retroperitoneal ganglioneuroma. CASE DESCRIPTION A 49-y-old female was admitted to our medical center with the complaint of abdominal pain. Abdominal ultrasound showed a hypoechoic solid lesion...

Retroperitoneal Ganglioneuroma Mimicking a Kidney Tumor. Case Report

BACKGROUND Ganglioneuroma (GN) is a rare benign tumor arising from the neural crest cells. The reported incidence of GN is one per million population. As a primary retroperitoneal tumor, it constitutes only a small percentage of 0.72 to 1.6%. GN can arise de novo or as a result of maturation of a neuroblastoma either spontaneously or after chemotherapy. The most common location is the posterior...

Diagnostic imaging findings of pelvic retroperitoneal ganglioneuroma in a child: a case report with the emphasis on initial ultrasound findings.

Ganglioneuromas are rare benign tumors of neural crest origin developed along the sympathetic chain. The pelvic retroperitoneum is the rarest location of these tumors. Clinically these tumors are commonly asypmtomatic even if they reach large sizes. Here we report the radiological features of a 16 year old boy with pathologically proven retroperitoneal ganglioneuroma that was detected initially...

A case of ganglioneuroma presenting abnormal FDG uptake.

We report a case of ganglioneuroma with abnormal 18F-fluorodeoxyglucose (FDG) uptake. A 26-year-old woman presented to the hospital with a slowly growing abdominal tumor without symptoms. She was diagnosed with neuroblastoma in childhood and treated by surgery and chemotherapy. Computed tomography (CT) revealed huge retroperitoneal tumors and fused 18F-fluorodeoxyglucose positron emission tomog...
