Abstract
- The vast majority of schwannomas occur on cranial nerves, and rarely in the retroperitoneum. Solitary schwannoma in the psoas muscle is extremely rare. The authors present a case of retroperitoneal neoplasm in the psoas muscle identified as schwannoma which is not associated with von Recklinghausen's disease. A 68 years old female patient was admitted because of low back pain and weakness at the left leg. CT and MRI revealed a large cystic mass with well-defined margin and multiple internal septation within the left psoas muscle. The tumor was totally extirpated and histologically confirmed as a schwannoma.
