Diverticulosis of the ileum is very uncommon. The differential diagnosis for any inflammatory process in the right lower quadrant of the abdomen includes appendicitis, Crohn's disease, and other infectious and inflammatory conditions of the terminal ileum and cecum. Diagnosis of small bowel diverticulitis is based on radiological findings, and computed tomography is the method of choice to demonstrate mural changes and the mesenteric extent of the inflammation. Preoperative knowledge of this condition may influence surgical and medical management.
