A 6-year-old girl was taken by ambulance to our hospital two days after she began to vomit and experience abdominal pain. She was diagnosed by abdominal ultrasonography and enhanced computed tomography as having torsion of the right ovary, and emergency surgery was performed. Laparoscopy revealed that the right ovary was twisted 720 degrees counterclockwise. The ovary did not show any malignant tumor, so only detorsion was performed. The left ovary had a normal appearance and there were no abnormal tumor markers or endocrine examination findings. Her postoperative recovery course was good, but 11 months later, the ovarian torsion recurred and emergency surgery was performed again. This time, the right ovary was twisted 360 degrees counterclockwise. After detorsion, we laparascopically fixed both ovaries by plication of the ovarian ligaments. The patient experienced no recurrence 1 year after the surgery. Torsion of a normal ovary is rare. Reported cases most often occur in prepubertal girls. Ovarian torsion has no specific symptoms, and is often diagnosed late. Although the role of ovary fixation in treating ovarian torsion remains unclear, plication of the ovarian ligaments may be a useful method because no recurrence has been subsequently reported.
