Chorioangioma associated with premature rupture of preterm membranes in pregnancy obtained by in vitro fertilization. Presentation of a case

Abstract

Dr Esmeralda López

Chorioangioma is the most common non-trophoblastic placental tumor, with an incidence of 1% of pregnancies. It was first described by Clarke in 1978. Although its etiology is not precisely known, it´s believed to consist of an abnormal proliferation of vessels in various stages of differentiation in the placental stroma. Prenatal diagnosis is made through ultrasound visualization of a rounded, hypoechoic, homogeneous-looking formation located on the fetal side of the placenta, with color Doppler inside.
