Severe fetal cardiomegaly caused by multiple non-giant placental chorioangiomas

Abstract

A pregnant woman was referred to our hospital due to fetal cardiomegaly. We recognised a dilated umbilical vein, which raised a suspicion of placental chorioangioma. A male neonate was delivered at 37 weeks of gestation. The cardiomegaly was gradually improved. Pathological examination identified five non-giant placental chorioangiomas. Multiple non-giant chorioangiomas may cause fetal complications despite the difficulty of prenatal diagnosis.

Localised chorioangiomatosis associated with fetal right‐sided cardiac dilatation

“…Isolated cardiac involvement in association with placental chorioangioma or chorioangiomatosis is uncommon. To the best of our knowledge, only one previous case has reported this finding 4 . Here, we describe a case of localised placental chorioangiomatosis associated with cardiomegaly and predominantly right ventricular (RV) dilatation.…”

“…However, Yamamoto et al . report one patient with cardiomegaly but an otherwise structurally normal heart 4 . The patient had no other associated abnormalities with no anaemia or thrombocytopenia.…”
