[Computed tomography of acute primary epiploic appendicitis].

Primary epiploic appendicitis is a rare but well known intraabdominal inflammatory process that characteristically presents with an onset of symptoms similar to diverticulitis, appendicitis and other abdominopelvic processes. CT findings are pathognomonic, consistent with a pericolonic oval shaped area of increased density with peritoneal thickening, and fat stranding. The condition is self limited and resolves completely within days under non-steroid antiinflammatory therapy.
