Abstract Objective: To investigate the prenatal MRI features of placental chorioangioma. Methods: Clinical and the prenatal MRI data from 11 cases of placental chorioangioma were analyzed retrospectively. Results: All cases are localized underneath the chorionic plate and protruded into the amniotic cavity. Five cases were localized near the root of umbilical cord, 6 at the root of the umbilical cord. The tumors were oval-like or irregular and mainly solid, showed isointense on T1WI and slight hypointense on T2WI. Among those complicated with hemorrhage, the lesions were heterogenous on both T1WI and T2WI, and showed increased signal intensity on DWI. Large branches arising from the umbilical blood vessels were showed in 7 lesions. Four cases were complicated with fetal abnormality, one with intrauterine fetal distress(IFD) and premature delivery, one with IFD, fetal anemia and cardiomegaly, one with intrauterine fetal death, and the last showed both the fetal biparietal diameter and head circumference were larger than that in normal fetus. Conclusion: The prenatal MRI demonstrate some morphological features of placental chorioangioma. When large branches arising from umbilical blood vessels were found inside the tumor, which indicates that there is a large amount of blood shunting.
