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
septations 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.
