Perirenal fat necrosis secondary to hemorrhagic pancreatitis, mimicking retroperitoneal liposarcoma: CT manifestation.
A case of resolving hemorrhagic pancreatitis resulting in massive left perirenal fat necrosis is reported. CT revealed a huge fat-containing mass that was thought to be retroperitoneal liposarcoma before operation. Pancreatitis with perirenal involvement is rarely encountered as a retroperitoneal mass.
