Description

A 30-year-old woman was admitted at 22 weeks' gestation for examining placental tumor. An ultrasound examination disclosed a solid placental tumor. The rich arterial flow in the tumor lead us to diagnose chorioangioma. The patient was re-admitted at 29 weeks' gestation due to the decrease of amniotic fluid. The fetus showed intrauterine growth restriction (IUGR). Non-stress test showed decreased long-term variability with severe variable decelerations. The patient underwent a cesarean section. The baby was a 728 g female. The placental tumor was dark red, indicating hemorrhagic infarction. Histopathologically, the tumor consisted of the various sized vascular tissue consistent with chorioangioma. The cause of IUGR and fetal distress was considered to be the aberrant placental function initiated by the infarction of chorioangioma.
