Vertigo and impaired pursuit eye movements in a small medial superior temporal infarction

Vertigo may occur in lesions involving the cerebral hemispheric regions such as the insular cortex, retroinsular area and temporo-parietal junction . However, no study has described vertigo and impaired pursuit eye movements as the only findings of supratentorial strokes. We report isolated vertigo and impaired pursuit eye movements to the lesion side in a patient with a small infarction restricted to the deep white matter of left superior temporal gyrus. This report suggests the subcortical location of the fibers to and from the human homologue of parieto-insular vestibular cortex and medial superior temporal (MST) area in monkeys.
A 75-year-old woman reported two episodes of spontaneous vertigo with illusory self-motion lasting several minutes. She denied associated headache, diplopia, dysarthria, visual field defects or limb weakness/sensory disturbance. She had a history of left cerebellar infarction 5 years before, but without neurological sequelae and had been...
