Cerebellar hypoplasia, dysplasia, and enlargement
Cerebellar hypoplasia is a feature of several neurodevelopmental disorders in which the cerebellum is small in size, but normal in shape. Disorganized development of the cerebellum causes cerebellar dysplasia in which the shape and “texture” of the cerebellum appear abnormal due to the presence of abnormal folia pattern or gray matter nodular heterotopia. Macrocerebellum is a rare malformation that may occur as an isolated finding or as part of a few syndromes.
