Abstract Sarcoidosis is a granulomatous disease that is known to rarely affect structures in the inner ear. We report the case of a 50-year-old female who developed bilateral vestibular hypofunction (BVH) during the clinical course of neurosarcoidosis. This case highlights the evolution of BVH from neurosarcoidosis and outcome of treatment. In addition to clinical assessment of vestibular function, video head impulse test was used to assess the function of all six semicircular canals. Before treatment, the vestibulo-ocular reflex (VOR) gain in all canals was low. Following treatment, the VOR gain improved in most of the canals to normal.
