A 37-year-old Asian woman, gravid 0 para 0, was admitted to our hospital at 34 weeks and 5 days of her pregnancy for management of preeclampsia. A few days after admission, she recognized diminished fetal movement, and a non-stress test revealed a non-reassuring fetal heart rate pattern with decreased variability. A female baby weighing 1840 g was delivered by emergency cesarean section with Apgar scores of 5 and 5 at 1 and 5 min, respectively. Significant neonatal anemia with a hemoglobin level of 4.3 g/dL was observed. The elevated level of hemoglobin F (HbF) in the maternal blood accounted for 4.6% (normal≦0.5%), and was indicative of the presence of fetomaternal hemorrhage (FMH). Microscopic examination of the placenta revealed chorioangioma. We report here a rare case of FMH with intraplacental chorioangioma, and discuss the relationship between these two pathologies.
