Abstract
Idiopathic Omental Infarct (IOI) is a rare cause of an acute abdomen that arises from an interruption of blood supply to the omentum. Since first case was described by Elitelin 1899, more than 300 cases have been published [1]. It can mimic serious surgical pathology. It occurs in <1% of appendicitis cases [2]. It’s challenge to diagnose, as features may mimic acute appendicitis and therefore in young patients, may only be discovered intra-operative. Here, we present a case of omental infarct in 26-year-old gentleman with no significant medical or surgical background who present with acute onset of right iliac fossa (RIF) pain. Examination revealed tenderness over the right iliac fossa and was having localized rebound. His inflammatory markers were high. He was successfully treated with laparoscopy surgery and he was subsequently discharged the following day.

Omental infarction is a rare cause of an acute abdomen that arises from an interruption of blood supply to the omentum and may be caused by torsion of the omentum around its vascular pedicle or venous outflow obstruction or vasculitis or thrombosis of the omental vessel, which can mimic the common presentations of acute appendicitis, acute cholecystitis or diverticulitis [3]
Omental infarction is a rare cause of acute abdomen, with an incidence equivalent to less than four cases per 1000 cases of appendicitis [2]
Summary
Omental infarction is a rare cause of an acute abdomen that arises from an interruption of blood supply to the omentum and may be caused by torsion of the omentum around its vascular pedicle or venous outflow obstruction or vasculitis or thrombosis of the omental vessel, which can mimic the common presentations of acute appendicitis, acute cholecystitis or diverticulitis [3]. Primary Omental infarct, with or without torsion occur commonly in obese patient and is associated with congenital anatomic variation [2]. 26-year-old gentleman with no significant medical or surgical history, presented via emergency department with history of sever RIF pain for 1 day. He has denied any previous abdominal trauma or recent surgery. No family history of any hematological disease On examination, he was conscious alert, vital signs within normal (HR: BPM, BP:117/66 mmHg, O2sat.:99% on Room air, T: 37.4 C), BMI: 37.3 abdominal examination revealed RIF tenderness with positive rebound tenderness. He was conscious alert, vital signs within normal (HR: BPM, BP:117/66 mmHg, O2sat.:99% on Room air, T: 37.4 C), BMI: 37.3 abdominal examination revealed RIF tenderness with positive rebound tenderness
