Abstract
Two cases of contralateral normal ovary torsion after adnexectomy or ovarian cystectomy were reported. Case 1 was an 11-year-old girl, who had a left adnexectomy for torsion of the normal ovary at 6 years old. She was referred to our hospital due to right back pain that persisted for 17 days. On admission, the right ovary (3-cm diameter) had been detected by abdominal CT. The back pain had continued and the second CT scan showed the right ovary had enlarged to 7 cm in diameter. Emergency laparotomy revealed that the right was twisted and necrotic, right adnexectomy was therefore performed. Case 2 was a 15-year-old girl, who had a left ovarian cystectomy at 4 years old. She presented with left abdominal pain, and abdominal CT scan demonstrated an enlarged ovary measuring 7 cm in size. Emergency laparoscopy revealed a left ovarian torsion and absence of the right ovary, detrosion and pexy of the left ovary were therefore performed. Normal ovary function was confirmed three months after the surgery. Clinical presentation of the normal ovarian torsion was nonspecific and early diagnosis was difficult. Whether the macroscopic appearance is necrotic or not, a detorsed ovary has a high potential for recovery. Torsion of a normal ovary in children should be managed conservatively.
