Left sided omental torsion with left inguinal hernia: a rare entity.

the omentum and the stranding continued inferiorly into left inguinal hernia sac (Fig. 2). The diagnosis of omental torsion with hernia was confirmed on laparotomy. Omental torsion usually occurs on the right side because of greater mobility of the right omentum. A left-sided omental torsion is rare and is difficult to diagnose clinically. Torsion may be primary, or secondary to underlying causes like hernia, tumors or adhesions [1]. Omental torsion results in vascular congestion with subsequent obstruction and omental infarction. Omental torsion is only rarely diagnosed preoperatively. CT is the investigation of choice for making the diagnosis. Omental torsion presents with characteristic fatty mass with central hyperdensity with surrounding whirling pattern [2].
