Chorioangioma
Medical condition / From Wikipedia, the free encyclopedia
Chorioangioma, or chorangioma, is a benign tumor of placenta. It is a hamartoma-like growth in the placenta consisting of blood vessels,[1] and is seen in approximately 0.5 to 1% pregnancies.[2] It is mostly diagnosed ultrasonically in the second trimester of pregnancy. Large chorioangiomas are known to cause complications in pregnancy, while the smaller ones are asymptomatic.
