Primary Segmental Infarction (PSI) of the greater omentum is rare. It usually presents as acute appendicitis and the diagnosis is made per operatively. We report a case of 22 years male who presented with history and clinical features suggestive of acute appendicitis. Laparoscopic appendicectomy was planned but during diagnostic laparoscopic phase, omentum was found infarcted in the right lower abdomen and the appendix was normal. Laparoscopic omentectomy of the infarcted segment was done and the patient had smooth recovery.
