Classification system for malformations of the cerebellum

Classification systems for malformations of the cerebellum are varied and are constantly being revised as greater understanding of the underlying genetics and embryology of the disorders is uncovered. A classification proposed by Barkovich et al in 2009 1 divides cerebellar malformations in two broad groups; those with cerebellar hypoplasia and; those with cerebellar dysplasia. 

  • cerebellar hypoplasia: reduced cerebellar volume 2
    • focal hypoplasia
      • isolated vermis
      • one hemisphere hypoplasia
    • generalized hypoplasia
  • cerebellar dysplasia: abnormal cerebellar foliation, fissuration, and architecture of the cerebellar white matter 2
