Hind brain agenesis a rare imaging findings in cerebro cerebellar lissencephalic syndrome.

A case report of cerebro cerebellar lissencephaly shows complete agenesis of cerebellum and brainstem which is rare imaging finding of group lissencephaly (type I lissencephaly). Though agenesis of cerebellum and brainstem were included in literature, in most of the cases we saw a hypoplasia or atrophy of cerebellum in lissencephaly syndrome. The CT scan findings of this patient shows features of lissencephaly with complete agenesis of brain stem and cerebellum associated with multiple congenital abnormalities.
