A Case of Angioleiomyoma of Retroperitoneum

Angioleiomyoma is a rare benign soft tissue tumor that originates from smooth muscle cells and contains thick-walled blood vessels. Few cases of angioleiomyoma have been described at sites other than the extremities and head. The female genital tract is rarely involved. We have experienced a case of retroperitoneal angioleiomyoma with abnormal MRI and CT findings, which was confused with ovarian malignancy.
