Atypical manifestation in vestibular schwannoma

Abstract

The cerebellopontine angle (CPA) is a cerebrospinal fluid-filled space, found at the junction between the cerebellum and pons. Vestibular schwannoma (VS) is the most common CPA tumor. Typical initial symptoms are unilateral or asymmetrical hearing impairment, tinnitus in the affected ear, or imbalance or vertigo. We report an unusual case of the patient who presented with right sensorineural hearing loss but was found to have left VS in the normal hearing ear.
