They are usually located in the head, neck and flexor surfaces of extremities. Schwannomas are very rare in the retroperitoneal region. Amongst all schwannomas 0.7% of benign ones and 1.7% of malignant ones are located in the retroperitoneum. Preoperative diagnosis is difficult because of vague symptoms. We report a case of retroperitonal schwannoma in a 70 years female patient because of its rarity and unusual location.
