Definitions |
By prenatal ultrasound, cerebellar hypoplasia is diagnosed if the cerebellum measures more than two standard deviations below the mean. In adults, cerebellar hypoplasia is typically diagnosed by computer tomography or magnetic resonance imaging. Cerebellar hypoplasia can be diagnosed if there is a small cerebellum with fissures of normal size compared with the folia (this is a distinguishing characteristic compared with cerebellar atrophy). Cerebellar hypoplasia (CH) refers to an underdevelopment of the cerebellum. This category of cerebellar malformation is distinct from Dandy Walker malformation in that it does not involve a concurrent enlargement of the posterior fossa, and almost all individuals exhibit cognitive and motor impairments. |
