Omental cake

Last revised by Dr Karwan T. Khoshnaw on 05 Jan 2022

Omental cake refers to infiltration of the omental fat by material of soft-tissue density. The appearances refer to the contiguous omental mass simulating the top of a cake. Masses on the peritoneal surfaces and malignant ascites may also be present. 

Pathology

The most common cause is metastases from ovarian, gastric, or colon cancer

Differential diagnosis

 

A core biopsy may be helpful if the primary tumor is unknown.
