Fetal anemia, cerebellar hemorrhage and hypoplasia associated with congenital Parvovirus infection

Abstract

We report a case of fetal cerebellar hemorrhage and hypoplasia, identified by fetal MRI after intrauterine blood transfusion at 21 weeks’ gestation for treatment of severe anemia due to congenital Parvovirus infection. Postnatal MRI confirmed atrophy of bilateral cerebellar hemispheres and inferior vermis. Cerebellar capillaries may be extremely susceptible to hemodynamic changes in the setting of intrauterine blood transfusion due to severe anemia. Although the correlation between fetal intracranial anomalies and Parvovirus infection remains unclear, in this population, a detailed evaluation of the brain parenchyma should be considered prior to and after intrauterine blood transfusion.
