Abstract:
A man, aged 74, presented with a rare clinical entity of an acute surgical abdomen similar to acute appendicitis. This case showed a non-Meckel's ileal diverticulitis that was complicated with a diverticular perforation and associated peritonitis. This is a very rare but potential life-threatening surgical emergency, mimicking the clinical presentation of acute appendicitis. The subject of small bowel non-Meckel's diverticulitis is reviewed because of the rarity of this condition and the diagnostic challenges it poses.
