Placental chorioangiomas are benign placental tumor. Most of them are asymptomatic with no need for specific treatment, while giant chorioangiomas may increase risk of pregnant complications. We describe a case of placental chorioangiomas diagnosed at 29+1 weeks of gestation. As the tumor progressively enlarged with polyhydramnios, further ultrasound examination indicated suggested sign of fetal hydrops. Following MDT discussion, cesarean section was performed with delivery of a female infant. Pathological examination of the placenta confirmed an infarcted chorioangioma. We highlight importance of close prenatal surveillance once the diagnosis of placental chorioangioma is made. Measurements vary depending on fetal maturity and the available neonatal support.
