Preoperative Diagnosis of Meckel's Diverticulitis Mimicking Appendicitis in a Young Adult: A Case Report.

Meckel's diverticulitis is a rare but important differential in patients presenting with right iliac fossa pain and is often initially mistaken for acute appendicitis. We report a case of a 22-year-old male patient who presented with symptoms consistent with appendicitis but was found on preoperative computed tomography (CT) to have Meckel's diverticulitis. He subsequently underwent surgical resection and made an uneventful recovery. This case highlights the diagnostic utility of CT in acute abdomen and the importance of considering Meckel's diverticulitis within the differential diagnosis of right iliac fossa pain in adult patients.
