Primary torsion of the greater omentum

Abstract

Primary torsion of the greater omentum is an uncommon cause of acute abdominal pain, often mimicking other acute abdominal conditions. There has been little in the English literature concerning diagnostic imaging of the torsion of the greater omentum because it is not usually diagnosed until surgically operated on for acute abdomen that has been interpreted as appendicitis. Resection of the infracted segment is the treatment of choice, offering rapid recovery and reducing the possibility of adhesion formation. We report a case of torsion of the greater omentum that was diagnosed correctly with preoperative computed tomography and discuss the therapeutic implications of this entity.
