　The prevalence of ovarian tumor torsion in women under 20 years old is estimated to be 4.9 /10,0000 cases, and the premenarcheal case is even less. We experienced a case in which an 11-year-old girl before menarche presented with a complaint of lower abdominal pain, which led to the diagnosis of ovarian tumor stem torsion combined with imperforate hymen. Ovarian tumor cystectomy combined with laparoscopic surgery and perforation of hymen were performed. Pathology result was ovarian mature teratoma. Normal menstruation was observed one month after the surgery. When examining premenarcheal pediatrics with lower abdominal pain, it is important to identify rare diseases such as imperforate hymen by taking a detailed history and performing a general medical examination.
