Placental chorioangiomas are malformations of the primitive angioblastic tissue. We present four different cases with different clinical spectrum. The first case is a 27 yo, G1P0, with 26 wo single pregnancy. Ultrasound examination showed posterior placenta with echogenic mass 4 × 4.5 cm located 2 cm to cord insertion. Power Doppler revealed vascular composition, and nutritious vessel was identified. Fetus was hydropic with venous Doppler alteration. Patient underwent to Fetoscopy and laser ablation of the communicant vessel. Three weeks later no Hidrops was identified and female infant was delivery at 37 weeks of gestation. Second case, was a 25 yo, G2P1C1, 22 wo pregnancy. Anterior placenta was identified with a mass located in the superior pole. Power Doppler showed vascular pattern and cord insertion 5 mm next to the mass. Polihydramnios and fetal normal anatomy were identified. Fetal surveillance was begun and three weeks later no polihydramnios was seen. Cesarean section at 38 week was performed and a healthy newborn was obtained. Third case was a 35 yo G2P0A1, with a 32 wo pregnancy. Fetal Hidrops was diagnosed and ultrasound revealed a chorioangioma of the posterior placenta. Patient was scheduled for laser ablation, but she developed gestational hypertension and proteinuria. Maternal severe edema was identified and mirror syndrome was diagnosed. Patient underwent to emergency c section and baby died two hours later. Fourth case was a 32 yo patient with 28 wo pregnancy. Placental chorionangioma was identified but no fetal compromise was seen. At 35 weeks, fetal Doppler with central dilation was diagnosed and pulsatile umbilical vein indicated emergency c section. Male infant 2300 grams was delivered and went to neonatal intensive care unit. Pathological correlation was obtained in all cases. In spite of benign pattern of placental choriangiomas as a tumor, fetal compromise should be considered for decision making and improving prognosis.
