If the diagnosis of peritonitis is made clinically, a CT scan is not necessary and generally delays surgical intervention without offering clinical advantage. However, CT scanning is indicated in all cases in which the diagnosis cannot be established on clinical grounds and the findings on abdominal plain films. CT scans of the abdomen and pelvis remain the diagnostic study of choice for peritoneal abscess and related visceral pathology.
