Omental infarction triggered by tight pants.

Idiopathic segmental infarction of the greater omentum (ISIGO) is a rare cause of acute abdomen. We report a case of ISIGO triggered by a unique etiology-wearing tight pants. A 75-year-old woman presented with acute lower abdominal and left flank pain with rebound tenderness. Her abdominal wall had a linear circumferential scar, which was compatible with a history of a tight elastic waistband of her pants weared around her waist. A computed tomographic (CT) scan showed a lesion of heterogeneous density located distal to the abdominal wall constriction. She was treated conservatively. Thus, combining the physical examination and CT findings is important for the diagnosis of ISIGO.
