Chorioangioma is the most common benign tumor of the placenta and associated with adverse perinatal outcome. The prevalence of chorioangioma of the placenta is about 1 percent. The most placental chorioangioma has no clinical significance. But the uncommon large (greater than 5 cm in diameter) chorioangioma may produce both maternal and fetal complications, such as polyhydramnios, preterm labor, fetal heart failure, hydrops fetalis, fetal growth restriction, fetal microangiopathic hemolytic anemia, fetal thrombocytopenia, toxemia of pregnancy, maternal thrombocytopenia, and maternal coagulopathy. The ultrasonography and Color Doppler are used for diagnosis of these lesions. If chorioangioma is suspected, Color Doppler study is informative to confirm the presence of the vascular channels. We report a case of multiple chorioangioma combined with oligohydramnios and discuss the noxious effects of this benign tumor on the mother and the fetus.
Key Words: Multiple Chorioangioma, Ultrasonography, Color Doppler, Oligohydramnios, Fetal death in utero
