A male in his 30s presented to the emergency department with a 1-day history of supra-umbilical pain migrating to the right iliac fossa. On examination, his abdomen was soft but tender with localised guarding in the right iliac fossa and a positive Rovsing’s sign. The patient was admitted under a presumptive diagnosis of acute appendicitis. A CT scan and ultrasound scan of the abdomen and pelvis showed no acute intra-abdominal pathology. He stayed in hospital for 2 days for observation without improvement of symptoms. A diagnostic laparoscopy was therefore performed that revealed an infarcted omentum adherent to the abdominal wall and ascending colon causing congestion of the appendix. The infarcted omentum was resected, and the appendix was removed. The CT images were reviewed by multiple consultant radiologists, but no positive findings were appreciated. This case report demonstrates the potential difficulty in diagnosing omental infarction clinically and radiologically.
