Abstract

Vestibular schwannoma is a benign tumor arising from the Schwann cells in the vestibular nerve. It causes unilateral hearing loss, tinnitus, vertigo and unsteadiness. The most common symptom is reduced hearing on the affected side. In most cases patients present complaining of hearing impairment or vertigo from which the otologist can get a clue to diagnose vestibular schwannoma. We experienced an unusual case of 45-year-old woman presented with recurrent mild dizziness without any hearing loss so the patient initially diagnosed with recurrent vestibulopathy. However, subsequent neurotologic evaluation and posterior fossa MRI scanning confirmed diagnosis of huge vestibular schwannoma originated from inferior vestibular nerve.
