Bilateral Ovarian Mature Cystic TeratomaA Rare Case Presentation

Abstract

The incidence of bilateral mature cystic teratoma of the ovary is only 10%. Ovarian mature cystic teratomas are common, benign, pelvic tumours and can be easily detected by ultrasonography. Recurrent ovarian teratomas are very rare, and cases of bilateral teratomas are even rarer. So, it is advisable to routinely check the ovary contralaterally during the surgical procedure along with careful pelvic sonographic examination of both the ovaries. Inadvertent extensive surgery should be avoided in this benign condition that might further compromise the fertility of young patients. We report a rare case of bilateral mature cystic teratoma of the ovary in a 28-year-old female, who presented to the gynaecologic outpatient department with complaints of intermittent dull aching, diffuse lower abdominal pain and dysmenorrhea for three months. Transvaginal ultrasonography revealed bilateral complex ovarian masses that raised suspicion of dermoid cysts with hypoechoic endometrial collections. Her Cancer Antigen 125 (CA-125) was normal. A bilateral ovarian cystectomy was performed and histopathology confirmed the diagnosis. This case highlights a rare occurrence of bilateral ovarian mature cystic teratoma, where cystectomy was performed to preserve the fertility in a young female.
