Omental torsion is a rare condition of acute abdomen. We present a 76 year-old
female with progressive abdominal discomfort and pain which lasted 3 days.
Physical examination showed tenderness and rebound pain localizing at the right
lower quadrant of the abdomen. Emergency operation was performed under the
impression of acute appendicitis. During the operation, a normal appendix and
omental torsion with ischemic change were noted. Partial omentectomy and
appendectomy with drainage were performed. She was discharged uneventfully. The
literature on omental torsion is reviewed.
