A case of placental chorioangiomatosis and frontal horn cystic lesions. Can frontal horn cysts be symptomatic?

Chorioangioma is a benign growth of the placenta. Diffuse placental chorioangioma is termed as chorioangiomatosis. We report a case of placental chorioangiomatosis with hydrops fetalis and frontal horn cystic lesions. Frontal horn cystic lesions are considered as benign lesions. Contrary to expectations, this neonate with frontal horn cysts developed seizures at 2~months of age.
