Computed tomography findings mimicking appendicitis as a manifestation of colorectal cancer

Published:February 26, 2009DOI:https://doi.org/10.1016/j.clinimag.2009.01.009

      Abstract

      The primary computed tomography (CT) signs of appendicitis can also be seen with other inflammatory or neoplastic processes. We report on two cases in which appendiceal dilatation and peri-appendiceal fluid or stranding were the dominant imaging manifestations of colorectal carcinoma in the ascending colon. This study highlights the need to closely examine the ascending colon in patients with a suspected CT diagnosis of acute appendicitis, since these findings may be secondary to an inconspicuous colorectal carcinoma.
