Classification system for malformations of the cerebellum
Updates to Article Attributes
Body
was changed:
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 intoin 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
-
generalisedgeneralized hypoplasia- with enlarged fourth ventricle
- normal fourth ventricle
- with normal pons
- with small pons
- normal foliation
-
pontocerebellar hypoplasias of Barth, types I and II
- cerebellar hypoplasias, not otherwise specified
-
pontocerebellar hypoplasias of Barth, types I and II
- normal foliation
- focal hypoplasia
- cerebellar dysplasia: abnormal cerebellar foliation, fissuration, and architecture of the cerebellar white matter 2
- focal dysplasia
- isolated vermian dysplasia
- molar tooth malformations including Joubert syndrome
- rhombencephalosynapsis
- isolated hemispheric dysplasia
- isolated vermian dysplasia
-
generalisedgeneralized dysplasia- congenital muscular dystrophies
- cytomegalovirus
- lissencephaly with RELN mutation
- lissencephaly with agenesis of corpus callosum and cerebellar dysplasia
- associated with diffuse cerebral polymicrogyria
- diffusely abnormal foliation
- focal dysplasia
