Lipomatous Lesions of the Colon

Lipomatous entities of the colon represent a small and definite nosologic group and include lipomatosis of ileocecal valve and lipomas; liposarcomas are extremely rare.CT colonography combines the possibility to measure tissue ­density to a direct visualization of the bowel wall; this ­technique allows an increasing sensitivity in the detection of fatty lesions and ensures a definitive diagnosis.This chapter aims to review the colonic lipomatous entities and their clinical features, to present the most important imaging findings, and to describe image interpretation and differential diagnosis.
