Multiple and Bilateral Mature Cystic Teratoma: A Rare Case Report

Mature teratomas, also known as dermoid cysts, are the most commonly occurring benign ovarian tumors in young and middle-aged women. Bilateral occurrence of mature teratomas is observed in 10% of cases. The incidence rate of mature teratomas is equal in both the right and left ovaries, and malignant transformation is observed in 1-3% of cases. At sonographic examination, mature cystic teratomas appear as cystic, solid, or heterogeneous masses containing areas of fat and calcification. Macroscopically, areas of fat are observed in 90% of cases, while areas of calcification are observed in 50% of them. In our presented case, a 28-year-old virgin female patient complained of pain in both adnexal regions, and tumor markers were found to be normal. During imaging, a complex mass measuring 65x47 mm was observed in the adjacent right ovarian parenchyma, and a complex mass measuring 44x41 mm was observed in the adjacent left ovarian parenchyma. However, during surgery, it was discovered that there were two additional teratomas adjacent to the cyst. Given that the presence of both bilateral and multiple mature teratomas is rare, decided to present this case.
