Omental Torsion and Infarction with Right Inguinal Hernia: A Case Report

Torsion of the greater omentum rarely causes acute abdominal pain. In this condition, the pedicle of the omental apron twists on its longer axis, resulting in compromised vascularity. On contrast-enhanced computed tomography (CT) of the abdomen, the presence of a mass with heterogeneous fat tissue and the whirl sign that resembles concentric lines inside the greater omentum are the typical characteristics of omental torsion (1). Although omental torsion is rarely diagnosed preoperatively, it is important for clinicians and radiologists to have knowledge of this condition because it mimics the common causes of acute surgical abdomen. Here, we report a rare case of surgically proven omental torsion and infarction associated with an untreated inguinal hernia, which were diagnosed with preoperative CT. CASE REPORT
