Omental infarction is one of the rare causes of acute abdomen which is often mistaken for acute appendicitis. Though there is no evidence of exact etiology, many of the predisposing factors have been attributed especially obesity in causation of this condition. It is common in young and middle age females but recently there is increase in the pediatric subjects due to significant lifestyle changes and thorough workup. Patients present with severe right sided pain abdomen rarely with fever or on the contralateral side. Signs of peritoneal irritation are present on examination which rarely leads to the accurate diagnosis of omental infarction. Computed tomography is gold standard tool to diagnose with specific hyper echoic fatty mass located between transverse or ascending colon and anterior abdominal wall. Though conservative treatment was practiced earlier, surgical modality with laparoscopic removal has warranted in faster recovery and clinical improvement with least complications.
