Pontocerebellar hypoplasia type 1

Pediatr Neurol. 2008 Oct;39(4):286-8. doi: 10.1016/j.pediatrneurol.2008.06.017.


Pontocerebellar hypoplasias are heterogeneous disorders that share a reduction in the size of brainstem and cerebellum. We describe a patient with features of the rare combination of pontocerebellar hypoplasia and spinal motor neuron disease. Parental consanguinity, low Apgar scores, facial weakness, dysphagia, tongue fasciculations, stridor, generalized hypotonia, severe muscle weakness, areflexia, and congenital joint contractures were evident. Cranial magnetic resonance imaging revealed a small cerebellum and brainstem, and a muscle biopsy revealed neurogenic changes. These abnormalities suggested pontocerebellar hypoplasia type 1.
