Rare cause of omental torsion secondary to left inguinoscrotal hernia

Abstract

Torsion of the greater omentum is a rare acute abdominal condition that is seldom diagnosed preoperatively. We present the unusual case of a 32-year-old male with secondary omental torsion due to a long-standing inguinoscrotal hernia. A contrast-enhanced computed tomography scan of the abdomen showed a heterogeneous fat-density mass, with a characteristic whirling pattern of concentric streaks within the greater omentum has been rarely described. An index of suspicion of omental torsion due to inguinoscrotal hernia as a differential diagnosis in the acute abdomen setting is necessary in the diagnosis and management of this rare combination.
