Extraperitoneal pelvic myolipoma.

Myolipoma is a very rare adipocytic tumor occurring most frequently in adults, and usually is located in the retroperitoneum or abdomen. It has been described in the retroperitoneum, spinal cord, orbita, breast, round ligament, subcutaneous tissue, pericardium, rectus sheath of the abdominal wall, and abdominal cavity with attachment to the abdominal wall. Most of these tumors are discovered incidentally and are large when discovered. Radiological findings are nonspecific due to the nonlipomatous component of the tumor. We present radiological findings of a large extraperitoneal pelvic myolipoma adjacent to the anterior abdominal wall, detected incidentally in an elderly woman with a presenting complaint of intractable hiccups.
