Choroid Plexus Papilloma Tumor of the Ovary: A Case Report

This is a case report of a 19-year-old nulligravid patient with a choroid plexus papilloma tumor in a mature cystic teratoma in the right adnexal area. The patient, who had abdominal pain and dyspepsia, showed a 9 cm diameter mass with a solid/cystic component, initially interpreted as a dermoid cyst in the right adnexal region. Mature cystic teratoma is a benign germ cell tumor and is common in women during the reproductive period. However, choroid plexus papilloma is a rare brain tumor. The diagnosis of ovarian choroid plexus papilloma can be made with imaging tests such as magnetic resonance imaging or computed tomography, and treatment is usually by surgical removal. Only four cases of ovarian teratoma with choroid plexus papilloma have been informed in the English literature, and this issue is the fifth.
