Torsion of lesser omentum: A rare presentation of acute abdomen

Intraperitoneal Focal Fat Infarction is a rare cause of acute abdomen. There are two types, Omental Torsion and Epiploic Appendagitis. We present a case of 19 years old male who presented to ER with severe pain in epigastrium and right iliac fossa. Clinical diagnosis of acute appendicitis was made, but epigastric pain remained unexplained. CT scan was reported as non-significant. Diagnostic Laparoscopy picked lesser omental infarction and acute appendicitis. Patient was successfully managed by Laparoscopic Surgery. Symptoms not explained by a single pathology should be thoroughly investigated. CT Scan is the best investigation. Laparoscopic surgery is an effective and safe approach for small segmental omental torsion.
