Omental torsion

A 65-year-old man presented to the emergency department complaining of right lower abdominal pain. Abdominal computed tomography showed a whirling pattern of fatty streaks and vessels in the greater omentum. From this typical finding, a diagnosis of omental torsion was made immediately, which was confirmed by subsequent surgery. We report a case of surgically and pathologically proven omental torsion that demonstrated a typical appearance on computed tomography and was diagnosed preoperatively.
