Omental Infarction is a rare cause of acute abdomen due to vascular compromise of the great omentum. When omentum infarction occurs exclusive of omental torsion, it is known as Primary Idiopathic Segmental Infarction. Here we present a case report of a middle age gentleman who presented to us with non–specific abdominal pain and discomfort. On relevant investigations, a diagnosis of Primary idiopathic segmental infarction of the greater omentum was made. The patient was managed on conservative lines. Here we emphasize on the need for considering this pathology as a possible differential diagnosis of acute abdomen and the overwhelmingly satisfactory results of conservative treatment protocols for the management of this disease.
