Isolated superior cerebellar artery infarction is rare, and the mechanism
is often not readily apparent. We describe a patient with an isolated
superior cerebellar artery infarction resulting from an ipsilateral
vertebral artery dissection. Angiography demonstrated intraluminal clot in
the superior cerebellar artery, suggesting artery- to-artery embolus as a
mechanism of this uncommon stroke syndrome.
