Abstract
Purpose
The purpose of this study was to evaluate the role of color Doppler imaging in the diagnosis and management of placental chorioangioma.
Methods
The medical records, sonographic reports, and sonograms of all pregnant women who had placental masses diagnosed in our sonography unit during the years 1992 through 2000 and had been evaluated using both gray‐scale and color Doppler sonography were included in this study. Subjective evaluation of the amount and distribution of intralesional vascularity by color Doppler imaging was made in all cases. Cases of chorioangioma of the placenta were compared with cases of placental hemorrhage or subchorionic hematoma. The outcomes of the pregnancies were also recorded.
Results
Fifteen cases of placental masses were evaluated; 8 of them were identified as placental hemorrhage or subchorionic hematoma on the basis of the sonographic findings. The other 7 cases were identified prenatally as placental chorioangioma, at a mean menstrual age of 23 weeks and a mean maternal age of 29 years. The mean size of the tumor was 6.5 cm (range, 4–13 cm). All cases of chorioangioma showed either substantial internal vascularity or a large feeding vessel within the tumor. Three infants were delivered at term with favorable outcome; 2 of them demonstrated reduction of the intratumoral blood flow during follow‐up. The other 4 cases were delivered at or before 32 weeks' menstrual age (1 intrauterine fetal death, 2 terminated pregnancies, and 1 normal infant). No case of placental hematoma demonstrated blood flow within the lesion or was associated with complications of the pregnancy.
Conclusions
Color Doppler imaging helps differentiate placental chorioangioma from other placental lesions and may be useful in the prenatal follow‐up of chorioangioma. © 2002 Wiley Periodicals, Inc.
