[Plasental chorioangioma (case report)].

Placental chorioangioma is the most common benign tumor of placenta, encountered in approximately 1% of all pregnancies. Clinical manifestations are rare and usually associated with tumors greater than 5 cm in diameter. They include polyhydramnios, congestive heart failure, anemia, prematurity, growth retardation, and intrauterine fetal death. We report a case of chorioangioma of the placenta in which ultrasonography and Doppler ultrasonography findings were useful in establishing the prenatal diagnosis.
