Sir,
Placental chorioangioma is an uncommon primary neoplasm of the placenta. We describe the antenatal color flow Doppler features of one such case.
A twenty-six-years old primigravida was referred for routine antenatal ultrasound scan at 25 weeks of gestation. Fetal growth parameters corresponded with period of gestation and amniotic fluid was adequate. The placenta was on the posterior uterine wall and showed a well-marginated, hypoechoic mass inside, measuring 6.5 x 6.4cm. A linear, anechoic, vascular channel was also seen coursing across it [Figure - 1]. Color Doppler on a Toshiba SSA 270 showed increased vascularity of the mass, in the central and peripheral portions [Figure - 2]. Both arterial and venous flows
were detected [Figure - 3]. Umbilical and uterine artery flow indices were normal. Follow-up scan after four weeks showed an increase in the size of the mass, which now measured 8.4 x 7.6 cm. The amniotic fluid was slightly less, with mild IUGR. The patient went into premature labor at 35 weeks and delivered a male baby weighing 2.2 kg by cesarian section. Histopathological examination of the placenta proved the mass to be a chorioangioma.
Placental chorioangioma may be associated with various fetal complications such as hydramnios, congestive heart failure, hydrops, anemia, prematurity and growth retardation when the size exceeds 5 cm in diameter. There are only few reports of color Doppler assessment of placental chorioangioma. While Grundy et al [1] and Hirata et al [2] found only arterial blood flow in the chorioangioma, Kung et al [3] did not find any vascularity in one patient and only peripheral venous flow in the second. Our study is unusual as it showed both central and peripheral flow with both arterial and venous characteristics. In patients with fetal and/or maternal complications, color Doppler may play a role in demonstrating the blood flow inside the mass. As for those without complications and with little or no blood flow, it is of limited use.
