- Vestibular schwannoma (VS) are benign neoplasms that arise from Schwann cells of the eighth cranial nerve. Although progressive unilateral hearing loss with dizziness or disequilibrium provides a high suspicion index of VS, vertigo is the symptom causing the most pronounced negative effect on quality of life in patients with VS. We report a 55-year-old woman with recurrent paroxysmal vertigo and hyperventilation-induced nystagmus due to VS, which improved by oxcarbazepine treatment. We suggest that episodic vertigo in VS may be ascribed to the ectopic paroxysmal neuronal discharge from the partially demyelinated vestibular nerve due to tumor compression.
