Congenital chylothorax presenting as hydrops fetalis. A case report.

A case of congenital chylothorax presented as polyhydramnios and massive fetal edema. The diagnosis was suspected prior to delivery on the basis of ultrasonography. Ultrasound was helpful in localizing the fluid for postnatal thoracentesis. Congenital chylothorax is part of the differential diagnosis of nonimmune hydrops fetalis.
