Abstract

Acute isolated vestibulopathy could be caused by either viral inflammation or ischemia. However, diagnosing ischemic vestibulopathy is difficult due to the ambiguity of the causal relationship between ischemia and peripheral vestibulopathy. We present here a patient with acute ischemic vestibulopathy without hearing loss caused by internal auditory artery occlusion, indirectly proven by the finding of a simultaneously developed silent cerebellar infarction. The details of this case suggest that patients with acute isolated peripheral vestibulopathy should be carefully evaluated for underlying causes, including vascular risk factors. Key Words: Vestibulopathy, Stroke, Internal auditory artery
