Omental cake
In radiology, omental cake is sign indicative of an abnormally thickened greater omentum. It refers to infiltration of the omental fat by material of soft-tissue density. Typically, it is caused by infiltration of metastatic tumours arising from the stomach, ovary, or colon. It can also result from tuberculous peritonitis. Another cause is lymphoma, in which omental caking is usually associated lymphadenopathy.
