CT findings of omental torsion and infarction - Case report and review of the literature

A 37-year-old woman presented with progressive diffuse abdominal pain. Computed tomography (CT) showed diffuse streaking of the greater omentum with a mass of fat density located anteriorly just below the umbilicus, showing a whirling pattern of concentric streaks. Surgery and pathology revealed torsion and infarction of the greater omentum. Because of its rarity and nonspecific clinical features, the diagnosis is seldom made preoperatively. We describe a patient with characteristic CT findings of omental torsion. Preoperative diagnosis is important since conservative management has been suggested. (C) 2003 Elsevier Science Inc.
