Abstract

Head-shaking test is a sensitive screening tool for a detection of peripheral and central vestibular system disease. Biphasic head-shaking nystagmus (b-HSN) is a rather uncommon phenomenon which was a combination of the paretic nystagmus and recovery nystagmus. We report characteristics of b-HSN in a patient with anterior inferior cerebellar artery infarction, whose only complaint was recurrent vertigo.
