Radiology · Abdominal imaging: omental caking

Sample item

A woman with ascites and a raised CA-125 has a CT showing a thick, nodular infiltrated omentum with tumour deposits on the peritoneal surfaces. What is this omental appearance called?

Original practice item, not a recalled exam question. Nothing here is recorded.

The answer and the reasoning

C. Omental caking in peritoneal carcinomatosis

A sheet of tumour replaces the omental fat as a thick plaque of soft tissue, called omental cake, and signals peritoneal metastases, commonly from ovarian cancer. Ascites often accompanies it.

Option by option

  • A. Epiploic appendagitis

    Epiploic appendagitis is a small focal fatty lesion beside the colon.

  • B. Normal fatty omentum

    A normal omentum is thin and fatty.

  • C. Omental caking in peritoneal carcinomatosis (correct)

    Correct. A thick infiltrated omentum is omental caking.

  • D. Mesenteric panniculitis

    Panniculitis is a mesenteric fat inflammation, not nodular plaque.
