Placental Chorioangioma with Nonimmune Hydrops Fetalis.

A 38-year-old woman was found to have a large placental chorioangioma. The fetus was studied using ultrasound. The pregnancy became complicated by hydrops fetalis, polyhydramnios, and abruptio placenta. The infant delivered at 29 weeks' gestational age. The neonatal course was complicated by nonimmune hydrops fetalis, respiratory distress syndrome, anemia, pulmonary hemorrhage, intraventricular hemorrhage, necrotizing enterocolitis, and bronchopulmonary dysplasia. The infant was discharged home with breastfeeding and off oxygen at 50 days of life. This case represents the multidisciplinary approach to the pregnancy complicated by a large placental chorioangioma and the resulting premature neonate with nonimmune hydrops fetalis.
