BACKGROUND Ancient schwannomas are degenerate peripheral nerve sheath tumors that very rarely occur in the retroperitoneum. They generally reach large proportions before producing symptoms due to mass effect. We describe three cases of retroperitoneal ancient schwannomas and discuss the diagnosis and management of these tumors. CASE PRESENTATIONS Three female patients with retroperitoneal anc...

Schwannoma is a benign peripheral nerve sheath tumor. It commonly occurs in head and neck region, upper extremities dorsolumbar spine. The giant schwannoma as such rare occurring We present series of three cases unusual locations, masquerading other soft tissue tumors. : Case 1: A 40-year-old male presented with large exophytic ulcerated growth on his left thigh. lesion was deep dermal location...

Pancreatic schwannomas are exceedingly uncommon neoplasms. According to a recent study in 2012, less than 50 cases of pancreatic schwannoma have been described in the English literature over the past thirty years. The vast majority of pancreatic schwannomas take place in the head and body of pancreas, respectively. Herein, we report the case of pancreatic tail ancient schwannoma in a 44-year-ol...

Schwannomas are usually benign, single, encapsulated, slow-growing tumours originating from cranial or spinal nerve sheaths. The vagus nerve involvement at the mediastinal inlet is very uncommon. For anatomical reasons, the resection of cervical and mediastinal schwannoma of the vagus nerve has a high risk of vocal fold paralysis. We describe the case of a 67-year-old female with a cervico-medi...

We report the CT findings in a patient with a lateral neck mass histologically diagnosed as a laryngeal schwannoma but presenting some uncommon CT features. CT showed unusual calcified components, very rarely observed and potentially misleading for diagnosis. However, this imaging feature can be found in ancient schwannomas. Our case is, therefore, a very rare one and reviews the main different...
