S (neurilemomas) are benign neurogenic tumours arising from Schwann cells of the peripheral nerve sheath. These tumours have a predilection for the head and neck, extremities and posterior mediastinum. Only 3% of schwannomas occur in the retroperitoneum, constituting approximately 4% of all retroperitoneal tumours. They occur without gender predominance in the 20to 50-year age group and are ass...

Herein, we present a case of a large purely cystic...
متن کاملSingle Stage Posterior Approach for Total Resection of Presacral Giant Schwannoma: A Technical Case Report

Giant presacral schwannoma has a risk for anterior surgical approach because of its massive size and proximity to abundant vascularity of presacral region. We report a single stage posterior approach for total resection of a giant presacral schwannoma. A 40-year-old female patient experienced left buttock pain an...
