COLOR FLOW MAPPING AND DOPPLER VELOCIMETRY IN THE DIAGNOSIS AND MANAGEMENT OF A PLACENTAL CHORIOANGIOMA ASSOCIATED WITH NONIMMUNE FETAL HYDROPS

Background: Placental chorioangiomas are the most common tumors of the placenta, occurring in 1% of all pregnancies. With the increasing use of ultrasound, prenatal recognition of these tumors is becoming more common. Case: A 36-year-old woman presented at 28 weeks' gestation wit h an intrauterine mass suggested by color flow and Doppler studies to be a vascular tumor. Because of the association of these findings to n onimmune fetal hydrops, management included umbilical blood sampling a nd intravascular transfusion for fetal anemia. This intervention tempo rarily corrected the hydrops and significantly prolonged the pregnancy . Conclusion: Color flow mapping and Doppler flow studies of intrauter ine tumors associated with fetal nonimmune hydrops can be helpful in b oth diagnosis and management.
