Abstract
|
|
|
|
Isolated vertigo and gait ataxia without other symptoms and signs have rarely been reported as manifestations of lateral medullary infarction. We report a patient with lateral medullary infarction who presented with vertigo and gait ataxia as only symptoms. Brain MRI showed a small infarction involving the most dorsolateral part of the right lateral medulla that corresponds to the vestibulocerebellar pathway. This unusual presentation seems to be related to a selective involvement of the far dorsolateral portion of the lateral medulla that corresponds to the central vestibular pathway.
