A Case of Hydrops Fetalis due to Placental Chorangiomatosis / 대한주산의학회잡지

Apart from the common etiologies of neonatal hydrops fetalis, a miscellaneous group of rare causes of them include abnormalities of the placenta, namely, chorangioma (chorioangioma). Chorangiomatosis is multiple small chorangiomas, a rare tumor occurring in 1% of pregnancies, of varying sizes in the placenta. When chorangioma is large enough it can cause high output cardiac failure of the fetus and results in non-immune hydrops. We report a case of neonatal hydrops fetalis caused by placental chorangiomatosis in which the placenta could have been easily overlooked. We suggest evaluating every placenta for biopsy in cases of neonatal hydrops fetalis especially when the other causes of hydrops fetalis have been ruled out.
