Question 11#

A 60-year-old woman presents with abdominal pain, and a CT scan reveals an omental mass. The most likely diagnosis is:

A. Desmoid tumor
B. Liposarcoma of the omentum
C. Omental infarction
D. Metastatic carcinoma

Correct Answer is D


Primary tumors of the omentum are rare, as is omental infarction. Metastatic tumors of the omentum are common, with metastatic ovarian carcinoma having the highest preponderance of omental involvement. Cancers of any portion of the gastrointestinal tract, as well as melanoma, uterine, and renal cancer, can metastasize to the omentum.
