[Dysarthria-clumsy hand syndrome caused by cerebellar infarction].

A 80 year old woman suddenly complained of dysarthria and clumsiness of the right hand. CT scan showed an infarct in the territory of the lateral branch of the right superior cerebellar artery. This dysarthria-clumsy hand syndrome in a patient with paroxysmal atrial fibrillation suggests that the likely cause was an embolus from the heart.
