Omental torsion secondary to inguinal hernia has rarely been reported as a cause of acute abdominalpain. However, in our case, omental infarction due to prolonged inguinal hernia-associatedomental torsion led to the formation of a large omental mass with marginal fibrosis, andthe patient presented with chronic abdominal pain. A 74-year-old man presented with complaintsof lower abdominal pain for 1 month; subsequently, bilateral inguinal hernias wereidentified through inguinal ultrasonography. CT scans revealed that the greater omentum wastrapped within the right inguinal canal, leading to omental torsion. The greater omentum, distalto the pedicle, appeared as a 30 cm-sized oblong fibrofatty mass in the right lower abdomenand pelvic cavity. Laparoscopic omentectomy with hernia repair was successfully performed.
