Аннотация
BACKGROUND: The objective was to evaluate imaging and neurodevelopmental features in patients prenatally diagnosed with isolated cerebellar hemorrhage using fetal magnetic resonance imaging (MRI).
METHODS: This was a retrospective-cohort case series of patients with isolated cerebellar hemorrhage who underwent fetal MRI over a 9-year period. Existing literature in the field is also reviewed.
RESULTS: Nine patients were identified; male predominance (n = 6) was noted. Injury patterns on fetal MRI included left cerebellar hemisphere only (n = 4), bilateral cerebellar hemispheres and vermis (n = 2), left cerebellar hemisphere and vermis (n = 1), right cerebellar hemisphere (n = 1), and right cerebellar hemisphere and vermis (n = 1). Overall, neurodevelopmental outcomes were favorable for 8 patients with available follow-up (range: 5 months-8 years). Eighty-seven point five percent had normal ambulation and all had normal speech. None required feeding or respiratory support. One patient had a diagnosis of Autism Spectrum Disorder. One patient had mild tremor with fine motor tasks. No patients had epilepsy.
CONCLUSIONS: While studies of preterm infants with isolated cerebellar hemorrhage report high risk for severe developmental delay, outcome in prenatally diagnosed isolated cerebellar hemorrhage is overall favorable.
