title: Prenatal diagnosis of placental chorioangioma: contribution of color Doppler ultrasound.
abstract: A case of placental chorioangioma was diagnosed at 35 weeks' gestation using color Doppler ultrasound. Color flow imaging showed an intraplacental hypoechoic mass fed directly by the anomalous chorionic tumor vessels arising from the insertion of the umbilical cord. Hypervascularization was present in some areas of the tumor. The diagnosis of typical 'angiomatous' type was confirmed by histopathological examination following delivery.
