Retroperitoneal schwannomas are rare tumors originating from Schwann cells of peripheral nerve ending and are uncommon (0.5-1.2%). Absence of typical clinical picture and lack of specific signs make preoperative diagnosis hard to ascertain. We report a case of a 45-year-old male who presented with constipation and difficulty in micturition for 5 days. Ultrasound abdomen showed a large mass of 13 cm × 10 cm with internal echoes posterior to urinary bladder and was confirmed by contrast enhanced computed tomography abdomen. A complete resection of mass without injuring the adjacent structures was carried out through a midline laparotomy. Histopathological evaluation and immunohistochemistry documented a benign retroperitoneal schwannoma.Retroperitoneal schwannomas are rare tumors originating from Schwann cells of peripheral nerve ending and are uncommon (0.5-1.2%).
