Jejunal diverticulitis is a rare condition which usually occurs in the elderly. Autopsy studies have revealed an incidence between 1.3% and 4.6% and radiological studies indicated an incidence between 0.02% and 2.3%. The condition is difficult to diagnose because its symptoms can mimic other conditions of acute abdomen. Perforation and other complications of diverticula are common in this condition. We report a patient with jejunal diverticulitis who was successfully treated surgically.
