Ileocecal abnormalities in appendiceal abscess.

The radiologic findings were reviewed in 16 patients with surgically proven appendiceal abscesses. The indirect indication of abscess comprised displacement of the cecum or small bowel, deformation of the cecum and filling defects or non-filling of the appendix. One or more of these abnormalities were observed in all the patients. In addition a fistula and a cavity were filled in 2 patients.
