title: Fat necrosis mimicking liposarcoma in a patient with pelvic lipomatosis. CT findings.
abstract: Pelvic lipomatosis is a rare condition characterized by an overgrowth of normal fat in the perirectal and perivesical spaces. The most important differential diagnosis is liposarcoma. We present a case of pelvic lipomatosis associated with a mass, which was diagnosed radiologically as a liposarcoma, but surgical biopsy result revealed fat necrosis.
