A 12-year-old girl with twisted parovarian cyst who admitted to GCMC because of lower abdominal pain was reported. She presented a smoothly margined, elastic hard mass in lower abdomen. The diagnosis of twisted ovarial cyst was made preoperatively from US and CT findings. At laparotomy, a huge cyst existed in the parovarium with normal right ovary. The cyst was removed with gangrenous ipsilateral salpinx. Clinically, it is difficult to differenciate the parovarian cyst from ovarial ones. It seems likely to parovarian cyst that the cystic mass located superior uterine fundus by US and a ipsilateral ovary is demonstrated by US or CT.
