Omental bleeding with spontaneously derotated torsion--a case report

A case of omental torsion seen in a 16 year old male is reported herein. Abdominal pain in the right lower quadrant suddenly developed just after the patient twisted his waist and an emergency laparotomy revealed a hemorrhagic mass at the edge of the right omentum, which was excised. Histological examination of the resected specimen showed hemorrhage without any venous thrombosis or infarction, possibly suggestive of omental torsion with early spontaneous derotation. The patient was successfully treated as a case of omental torsion.
