Meckel's diverticulum is the most common congenital gastrointestinal anomaly, and 2-4% of patients with a Meckel's diverticulum will subsequently develop complications, including intestinal hemorrhage, intestinal obstruction, and diverticulitis. Meckel's diverticulitis is infrequently included in the differential diagnosis of abdominal pain in older adults. We present a case of Meckel's diverticulitis in a 74 year-old male who presented with non-specific abdominal pain and angina. Here, multi-detector computed tomography (MD-CT) imaging provided a pre-operative diagnosis of Meckel's diverticulitis. We then offer a review of the epidemiology, anatomy, radiologic findings, and differential diagnosis of Meckel's diverticulitis. This case presents coronal and sagittal MD-CT reconstructions of Meckel's diverticulitis that have yet to be well-described in the literature.
