Retroperitoneal schwannomas are rare tumors difficult to diagnose preoperatively. It may originate at the cranial nerves or nerves of the upper extremities, but origin along the nerves of the retroperitoneal space is very rare. Most of the retroperitoneal schwannomas are benign neoplasm. These tumor can be misdiagnosed as adnexal mass or carcinoma. Venous thromboembolism or pulmonary embolism is increasingly recognized as a common complication in patients with malignant disease. We report a 37-year-old woman presented with pulmonary thromboembolism and a pelvic mass which was incidentally found and misdiagnosed as ovarian cancer. Histopathologic results of the extirpated mass turned out to be a benign schwannoma.
