Case Discussion

Diverticulitis is a complication of diverticulosis, and most commonly involves the sigmoid, more commonly in the left colon and never the rectum. It may be complicated with abscess, perforation or fistula formation.

The presence of other diverticulae supports the diagnosis of diverticulitis in this case of segmental colonic inflammation.
