A 48 year old woman developed an acute vestibular syndrome associated with upside down vision a few hours after minor cervical trauma. Magnetic resonance imaging showed an ischaemic lesion in the territory of the medial branch of the posterior inferior cerebellar artery. An arteriogram showed a dissection of the left extracranial vertebral artery.Since the advent of CT small cerebellar strokes are known to present as isolated vestibular, syndromes."5 The pathophysiology of these labyrinthine-like syndromes has recently been clarified from the results ofmagnetic resonance imaging (MRI) and pathological studies.'7 In most cases they result from infarction associated with the medial branch of the posterior inferior cerebellar artery.67 We report a case of such a stroke due to dissection of a vertebral artery after a closed head injury.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations鈥揷itations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
