Idiopathic Omental Infarction to Be a Rare Cause of Acute Abdomen: A Case Report

Omental infarction is a rare entity, representing hemorrhagic omental necrosis as a result of impaired omental perfusion. It can occur secondary to omental torsion or to inflammatory and neoplastic infiltration of the omental segment from adjacent organs. If the foregoing reasons can be excluded, omental infarction is called primary or idiopathic omental infarction. Occlusions of small omental arteries are rare and may be found in patients with thromboembolic disease, arteriolosclerosis, arteritis, or amyloidosis. The author presents a case of idiopathic omental infarction in a 66-year-old male presenting with abdominal pain. The patients underwent an emergent operation and recovered without any complication after surgery.
