Abstract

Solitary caecal diverticulum is an uncommon entity and therefore difficult to diagnose except at surgery. Caecal diverticulitis is an infrequent cause of acute abdomen and usually presents in a manner similar to acute appendicitis. It is extremely difficult to differentiate it preoperative from acute appendicitis and such distinction is usually made in the operating room. The optimal management of this clinical condition is still controversial, ranging from conservative treatment with antibiotics to aggressive surgical resections.

We report a case of a 61 year old Caucasian who presented with acute onset right iliac fossa pain indistinguishable from acute appendicitis. The true diagnosis of a perforated acute caecal diverticulitis with an abscess mass was only made at operation in the presence of a macroscopically normal appendix. We reviewed the literature to highlight the difficulty of a preoperative diagnosis and the need for a high index of suspicion especially in the older age group presenting in manner similar to acute appendicitis.
