Abstract

Bilateral vestibulopathy (BV) is a clinical entity with impaired function of bilateral peripheral vestibular system, which is characterized by movement-induced vertigo, oscillopsia and gait unsteadiness. Among various etiologies of BV, alcohol and vitamin B deficiency has rarely been reported. We experienced a case of BV with vitamin B deficiency in a 24-year-old man who was previously exposed to alcohol. He had osillopsia and gait unsteadiness as a primary symptom, and was treated successfully with vestibular rehabilitation and vitamin supplement. Bithermal caloric test, rotatory chair test and head impulse test showed the result compatible with BV.
