P17.07: Chorioangiomas with signs of fetal compromise on ultrasound evaluation: a case series

Chorioangiomas (ChAs) are benign placental tumors that occur in around 0.6% of pregnancies (1). Giant ChAs, which are greater than 4cm in diameter, can disrupt fetal circulation and pregnancies with this condition are more likely to present growth restriction, fetal heart failure, polyhydramnios, fetal anemia, premature delivery, and intra-uterine demise (IUD) (2). When ChAs are diagnosed antenatally, close ultrasound examination is recommended, but the optimal ultrasound management is unknown (3). We report our experience in the management of four cases of ChAs diagnosed at our center between 2016 and 2019. All cases were diagnosed at the routine second trimester scan and followed thereafter with serial ultrasounds performed at least every two weeks to evaluate fetal growth, and wellbeing, and systematic Doppler evaluation of the middle cerebral artery peak systematic velocity (MCA PSV), ductus venosus (DV), and umbilical artery (UA). The diagnoses of ChA were confirmed by placental pathologic examination. CASE 1
