Mature cystic ovarian teratoma invading the bladder: A rare case report

Mature cystic teratomas (MCTs) are the most common type of ovarian germ-cell tumor, rarely showing bladder invasion. We present a case of a premenopausal 47-year-old female who suffered from increased frequency to urinate followed by lower abdominal pain for 3 years. To the best of our knowledge, we present the first case of mature cystic ovarian teratoma invading the bladder, associated with lower abdominal pain after urination. Open partial cystectomy and lesion side accessory resection were done, which seemed effective in managing MCT that invades bladder.
