<unk>  arises from the cerebellar stem cells, which are normally involved in the anatomical development of the cerebellum and posterior cranial fossa structures.<unk>  is an invasive and rapidly growing brain tumor which may metastasize to different organs of the body. Genes involved in the pathogenesis of<unk>  include CTNNB1 gene, PTCH1 gene, MLL2 gene, SMARCA4 gene, DDX3X gene, CTDNEP1 gene, KDM6A gene, and TBR1 gene.<unk> s are associated with a number of syndromes that include Gorlin syndrome and Turcot syndrome. On gross pathology, a pink, solid, and well circumscribed mass is a characteristic finding of<unk> . On microscopic histopathological analysis, round tumor cells, elevated mitotic rate, increased nucleus:cytoplasmic ratio, and Homer-Wright rosettes are characteristic findings of<unk> .
