Abstract

Vestibular schwannoma, also known as acoustic neuroma, is a rare benign brainstem tumor surrounding the vestibular division of the 8th cranial nerve. The presenting symptoms are hearing loss, tinnitus, and dizziness. Unabated growth can compress 5th (trigeminal nerve) and 7th (facial nerve) cranial nerve, which can cause nerve dysfunction such as orofacial pain, sensory abnormalities, or trigeminal neuralgia. We report a 51-year-old woman who presented with orofacial dysesthesia on her left side of the face with abnormal findings on 5th cranial nerve and 8th (vestibulocochlear nerve) cranial nerve examination. Brain magnetic resonance imaging scan revealed cerebellopontine angle tumor. She was referred to a neurosurgeon and diagnosed with vestibular schwannoma.
