Diverticulum of the cecum is a rare condition that was first described in 1912 by Potier.1When it manifests in the presence of diffuse diverticulosis of the colon, it is likely to be a false diverticulum, consisting of an outpouching of mucosa through a weakened area in the muscularis. However, an isolated cecal diverticulum in the absence of generalized colonic involvement is more likely to be a true diverticulum. In this case, we had a true diverticulum of the cecum as confirmed by histopathological analysis. It has been argued that right-sided diverticulitis has a benign natural history, and the same may hold true for isolated cecal diverticulitis.2,3However, in a large series of 112 cases, aggressive management with segmental resection and anastomosis was advocated because of a high recurrence rate (25%) with conservative management.4Diverticulectomy is an option if it can be accomplished without encroaching on the ileocecal valve or endangering the blood supply of the cecum.5In the case at hand, extensive gangrene of the diverticulum with phlegmon formation involving a large part of the cecum as well as the presence of a second diverticulum at the ileocecal junction precluded a diverticulectomy. Cecal diverticulitis is more often than not discovered during surgery for presumed appendicitis, and awareness of this diagnostic pitfall can better prepare the surgeon and the patient regarding therapeutic options.
