Pseudovestibular neuritis associated with isolated insular stroke

Damage to the cerebellum or brainstem can often cause vestibular dysfunction. Although rare, central rotational vertigo following cerebral cortical lesions has also been reported [1, 4, 5, 7]. However, no report has documented objective nystagmus associated with central rotational vertigo in cortical stroke. We describe a patient with rotational vertigo who showed mixed horizontal and torsional spontaneous nystagmus mimicking peripheral vestibulopathy in isolated insular infarction.
