Bottom Line: The placenta was very large, weighing 1416 g.These venous channels were dilated and tortuous and led into the placenta.In conclusion, prenatal diagnosis of placentomegaly and markedly-dilated chorionic vessels requires assessment of growth, anemia and DIC of the fetus and the newborn infant.

ABSTRACT
We reported a very rare case with placentomegaly and markedly-dilated chorionic vessels. A 23-year-old Japanese pregnant woman was referred to our hospital at 32 weeks of gestation because of suspected dilatation of the umbilical vein. Ultrasound revealed fetal growth restriction with no fetal anomalies. The placenta was thick. The umbilical cord had two arteries and one vein, and marginal insertion of the umbilical cord in the placenta was suspected. A lot of remarkably tortuous tubular structures were observed on the surface of the placenta. Slow blood flow, indemonstrable with color Doppler, was observed within them. Labor started suddenly and progressed very rapidly at 33 weeks of gestation. A female infant weighing 1524 g was delivered. The infant had no malformations. However, she showed hypotension, anemia and DIC and required blood transfusion. The placenta was very large, weighing 1416 g. On the fetal surface, numerous dilated and tortuous vessels were observed, arising from a vein that was connected to the umbilical vein. These venous channels were dilated and tortuous and led into the placenta. In conclusion, prenatal diagnosis of placentomegaly and markedly-dilated chorionic vessels requires assessment of growth, anemia and DIC of the fetus and the newborn infant.

Fig7: Intraplacental vessels were extremely dilated and walls of these vessels were fused (red arrow).

Mentions: Histologic examination revealed necrosis in the decidua. The villi were normally formed and hydropic villi were not observed (Figure 6). Part of the intervillous spaces were occluded by precipitated fibrin and the villous stroma were edematous. Infarction was widely noted in the amnion. Intraplacental vessels were extremely dilated and walls of these vessels were fused (Figure 7). On the other hand, the umbilical arteries and vein, and parenchyma of the maternal side of the placenta had no anomalies.Figure 6
