(A) Contrast-enhanced right parasagittal CT section through the abdomen and pelvis shows a huge, well-defined, low density, nonenhancing, intraperitoneal, mass lesion extending from the diaphragm down to pelvis. Note the fibrous septa and a calcified focus (arrow). No evidence of inflammatory reaction or infiltration of surrounding structures. (B) Contrast-enhanced axial CT section through the abdomen and pelvis: The well demarcated, low attenuating mass lesion is compressing the bowel loops rather than infiltrating them (arrows). No extension to the retroperitoneal spaces. The retroperitoneal structures and the bowel loops are displaced posterolateraly (arrows). No evidence of any obstructive compression on gastrointestinal or urinary tract organs.

There was no evidence of inflammatory reaction or infiltration of surrounding structures or tissues (Fig. 1A). There was no evidence of any obstructive compression on gastrointestinal or urinary tract organs (Fig. 1B).
Macroscopic view from the cut of the large 4 kilograms tan and gray color glistening surfaced encapsulated moderately firm mass. The cut sections show homogenous yellowish tan soft surfaces.

The cut sections of the mass showed homogenous yellowish tan soft surfaces (Fig. 2).
Microscopic section of the mass lesion shows tumor composed of large nodules and sheet of mature adipocytes without atypia, separated by thin fibrous bands. Negative for malignancy.
