Abstract

Vestibular schwannoma (VS) is a rare benign tumor arising from the vestibular portion of the 8th cranial nerve. Patients with VS complain of diverse symptoms, such as asymmetrical hearing loss, tinnitus, vertigo, and unsteadiness. The most common symptom of VS is unilateral and gradual loss of hearing, which may also be associated with tinnitus. We experienced an unusual case of 62-year-old woman, who presented with acute vertigo without any typical otologic symptoms of hearing loss and tinnitus. Because of the unusual symptom, the patient was initially diagnosed with vestibular neuronitis. However, atypical nystagmus was presented after head shaking test. Internal auditory canal MRI scanning confirmed the diagnosis of VS. We removed the patient's VS by middle cranial fossa approach. We present this case with a review of relevant peer-reviewed medical articles and literature.
