Case Series: Diverticulitis in the Young

Abstract Diverticulitis has long been regarded as a disease of the elderly, but its incidence has been increasing in those under age 40. Younger patients with diverticulitis are more likely to be male and obese. They often have atypical presentations, and 25% may have right lower quadrant pain. Not surprisingly, the condition is often misdiagnosed, resulting in unnecessary surgery. An abdominal CT scan is the modality of choice for diagnosis, but the most important diagnostic step is simply to include diverticulitis on the differential diagnosis of a young person with lower abdominal pain.
