CT of appendicitis.
The CT findings of 38 consecutive patients with acute appendicitis are analyzed, described, and illustrated. CT showed intraabdominal disease in 92% of patients and made a specific diagnosis of appendicitis in 79% of cases. The most common CT findings were pericecal inflammation (68%), abscess (55%), calcified appendicolith (23%), and an abnormal appendix (18%). CT had a sensitivity similar to that of contrast enema examinations, but it correlated much better with the surgical findings in detecting the precise nature, extent, and location of the disease process. Normal CT does not exclude appendicitis, since mild forms without periappendiceal disease may escape detection.
