A 45-year-old man visited complaining of swelling of his left lower extremity. Abdominal computed tomography revealed a left inguinal tumor compressed the external iliac vein. Venography showed a sandglass like stenosis of iliac vein. The tumor was 5 cm in size, and showed high intensity in T1-weighted magnetic resonance imaging. We diagnosed that is retroperitoneal lipoma, and performed a tumor resection. The tumor was yellow and its surface was smooth with a thin capsule. A part of tumor was adhered to external iliac vascular sheath, and we suppose that is the origin of the tumor. Histopathological diagnosis was benign lipoma.
