Preoperative ultrasound diagnosis of appendiceal diverticulitis in a CT limited setting: A case report.

Appendiceal diverticulitis is a rare inflammatory condition that often mimics acute appendicitis but carries a higher risk of complications. We report a 50-year-old female presenting with chronic right lower quadrant pain for six months without systemic symptoms. Ultrasound revealed a focal diverticular outpouching from the mid appendiceal segment with surrounding inflammation and no fluid collection. In a resource-limited setting, the patient underwent open surgery based on ultrasound findings. The postoperative course was uneventful, and she was discharged on the second day. Intraoperative and histopathologic findings confirmed appendiceal diverticulitis without malignancy. This case highlights the value of ultrasound in diagnosing appendiceal diverticulitis when computed tomography is unavailable.
