OC129: Comparison of fetal umbilical and cerebral Doppler measurements and placental‐cerebral ratio in diabetic and non‐diabetic pregnancies at term

Results: 69/73 dermoid cysts were diagnosed at ultrasonography analysis but 4/73 mature cystic teratomas had different preoperative sonographic diagnosis (1 ovarian fibroma, 2 serous cysts, 1 endometrioma). The histological diagnosis was confirmed in 69/70 cysts suspected to be dermoid at sonography: 1 patient had diagnosis of bilateral dermoid cysts but one of these was a serous cyst. Conclusions: This study demonstrates that ultrasonography has a sensitivity of 94.5% and a positive predictive value of 98.5% in diagnosis of dermoid ovarian cysts.
