A Case of Perforated Jejunal Diverticulum: An Unexpected Cause of Pneumoperitoneum in a Patient Presenting with an Acute Abdomen.

BACKGROUND Jejunal diverticulosis is a rare clinical condition, and the majority of patients are asymptomatic. However, some patients can develop serious complications, including perforation. We report the case of a 74-year-old female patient with a perforated jejunal diverticulum who presented with an 'acute abdomen' and with pneumoperitoneum on X-ray radiography.
