Prenatal sonographic appearance of hemorrhagic cerebellar infarction.

ABSTRACT

To date, the prenatal diagnosis of cerebellar hemorrhage has been limited to isolated case reports, which have demonstrated either a hyperechoic cerebellar hemisphere or a hyperechoic mass within the cerebellum in near-term fetuses. We demonstrate the ultrasonographic findings of intracerebellar hemorrhagic infarction in a fetus at approximately 21 weeks' gestation. In contrast to previous case reports, the hemorrhagic infarcts seen in our case were hypoechoic.
