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

Omental torsion and infarction are rare causes of acute abdominal pain, and it is often difficult to diagnose these conditions preoperatively. There are several reports showing that computed tomography is useful to diagnose these conditions. Here, we report a case of a 59-year-old man with omental infarction due to secondary omental torsion associated with an untreated inguinal hernia. Preoperative computed tomography showed a fatty mass in the right lower quadrant and a right inguinal hernia containing torsion of the greater omentum. He underwent laparoscopic partial omentectomy and herniorrhaphy, and the postoperative course was uneventful.
