Prenatal Diagnosis and Neurodevelopmental Outcome in Isolated Cerebellar Hypoplasia of Suspected Hemorrhagic Etiology: a Retrospective Cohort Study

In this monocentric retrospective study, we describe the neurodevelopmental outcomes in a series of children with isolated cerebellar hypoplasia of presumably hemorrhagic origin prenatally detected with fetal magnetic resonance imaging (fMRI). We retrospectively reviewed the charts of all the pregnant women who were referred for a neurological consultation, diagnosed with fetal encephalic malformation/disruption between 2010 and 2020 in the Fetal Therapy Unit of our institution. Fetal MRI (fMRI) was performed in all the pregnancies. Fetuses with cerebellar hypoplasia presumably of hemorrhagic origin were selected for the study. Fetuses exposed to alcohol or with additional malformations in other cerebral or body areas were excluded. All the infants received the postpartum follow-up care adopted in our center, including post-natal MRI, serial neurological examinations, standardized neurodevelopmental tests, and regular parental interviews. Cognitive functions were tested with GRIFFITHS II, WPPSI-III, and WISC-IV according to the child's age. A total of 14 pregnant women out of 479 fetal consultations were eligible and included in the study group. In 57% of cases, the etiology of the hemorrhage was unknown. In 21% of cases, it was attributed to a blood transfusion, while in the remain...
