Pak J Radiol May ;30(4):286-8.

A 52-year-old man presented to the the emergency department with severe right-sided abdominal pain. Murphy`s sign was elicited. A presumptive diagnosis of acute cholecystitis was made . Ultrasound of the abdomen revealed normal appearance of gallbladder . CECT scan of his abdomen and pelvis demonstrated focal ,non enhancing ,mass like mesenteric fat stranding & thickening of greater omentum in right perihepatic region .The patient was diagnosed with idiopathic segmental infarction of greater omentum. (ISIGO) is a rare cause of right-sided abdominal pain, mimicking acute surgical pathologies .CT features can be diagnostic, but due to its rarity the diagnosis is often missed. We present a case of ISIGO and discuss the utility of CT scan & role of conservative management of ISIGO . The literature about the incidence, pathogenesis, and management of omental infarction is reviewed and presented to the reader.
