Primary linitis plastica of the rectum

The term linitis plastica describes an infiltrating, anaplastic, scirrhous adenocarcinoma that generally occurs in a hollow viscus resulting in a relatively rigid, shrunken organ. Although the stomach is the most common site of linitis plastica, accounting for 99% of these lesions, the colon can be similarly affected. Primary colonic linitis plastica is a rare entity with only about 40 unequivocal reported cases in the literature. A recent case of primary colonic linitis plastica is described with emphasis on the computed tomographic (CT) findings.
