CT findings of a giant retroperitoneal liposarcoma; our experience at services hospital, Lahore

ABSTRACT

Liposarcoma is the most common primary neoplasm of mesodermal origin derived from adipose tissue. It is a slow-growing tumor with a propensity to displace rather than invade adjacent structures. This article reports the CT findings of retroperitoneal liposarcoma in one patient. CT scan revealed a huge hypodense expansile mass lesion with multiple hyperdense septation inside it, giving a whorly appearance to the mass. The mass was having mainly fat [attenuation. The mass appeared to be extending from the under surface of right hemidiaphragm to the right iliac fossa. The mass displaced all the abdominal viscerae and major vessels to the left side of the abdominal cavity, origin being retroperitoneum with most probable epicenter in right renal fossa
