Posterior Circulation Stroke and Vestibular Syndromes

Show Summary Details

Vertigo is a common symptom associated with stroke in the posterior circulation. Since the circulation to the inner ear arises from the posterior circulation system, vertigo due to posterior circulation stroke can be peripheral or central origin. Although vertigo ascribed to posterior circulation stroke is usually associated with other neurological symptoms or signs, small infarcts in the posterior circulation territory can present with vertigo without other localizing symptoms. Head impulse test can differentiate acute isolated vertigo due to posterior circulation stroke from more benign disorders involving the inner ear. Sometimes isolated vertigo and/or hearing loss can be the initial symptom of impending stroke (particularly within the territory of the anterior inferior cerebellar artery). In this case the MRI is normal and the clinician must rely on other clinical features in order to make the diagnosis. Herein the authors review the keys to the diagnosis of vascular vestibular syndromes due to posterior circulation stroke involving the brainstem and cerebellum.
