Abstract
A 77-year-old man developed acute vertigo and unsteady gait. Neurological examination revealed spontaneous left-beating nystagmus in the primary position. He fell to the left when walking without support. Magnetic resonance imaging showed an acute infarction involving the right parieto-temporal lobe. Although the vertigo and unsteady gait are most often associated with vestibular disorders involving the infratentorial structures, those may occur in cerebral infarction of the parieto-temporal lobe.
