MRI features of right cerebellar atrophy are most likely due to crossed cerebellar diaschisis secondary to contralateral left supratentorial cerebral infarction in childhood (Dyke-Davidoff-Masson syndrome).
Crossed cerebellar diaschisisrefers to a depression in function, metabolism, and perfusion affecting a cerebellar hemisphere occurring as a result of a contralateral focal supratentorial lesion (usually an infarct). The mechanism is thought to be an interruption of cortico-ponto-cerebellar white matter tracts, which then results in deafferentationdifferentiation and hypometabolism of the contralateral cerebellar hemisphere.
