Omental Fat Torsion: A Rare Mimicker of a Common Condition

Abstract

Acute abdomen is a common emergency condition affecting young adults, and the first consideration is usually aimed to rule out acute appendicitis in this age group. Omental fat torsion has emerged as one of the rare etiologies of acute abdomen in the younger population. It warrants serious consideration as it closely mimics acute appendicitis in its clinical presentation. Herein we report a case of omental fat torsion in a 22-year-old male patient who presented with an acute right-sided lower abdominal pain which was highly suggestive of acute appendicitis. However, the diagnostic laparoscopy revealed a normally looking appendix and terminal ileum with an infarcted omental segment on the right side of the greater omentum. A laparoscopic omentectomy and an appendectomy were performed with an uneventful postoperative recovery. The pathology report confirmed omental fat infarction and a normal appendix. This case highlights omental fat infarction as a rare etiology of acute abdomen in a young male patient.
