A Case of Idiopathic Omental Infarction Improved with Conservative Treatment

Abstract

A 30-year-old man was referred to us because of suspected acute appendicitis, having complained of right lower abdominal pain lasting for 3 days. Palpation showed tenderness and rebound tenderness located in the right lower abdomen, and biochemical findings showed a remarkable increase in inflammatory reaction. An abdominal computed tomography (CT) examination showed increased fat density located on the ventral side of the ascending colon and directly inferior to the abdominal wall. Since the patient had no history of abdominal surgery, abdominal trauma, or omental torsion, we made the diagnosis of idiopathic omental infarction. After admission, conservative treatment with fasting and antibiotics was initiated. The symptoms gradually improved, and she was discharged on the 12^th day after admission. In this study, we report a case of idiopathic omental infarction that improved following conservative treatment.
