Normal pressure hydrocephalus after gamma knife radiosurgery in a patient with vestibular schwannoma

Abstract

Background Vestibular schwannoma is a benign, usually slow-growing tumor, which develops from Schwann cells of the eighth cranial nerve. Case Report The treatment options for the schwannoma are surgical removal or gamma knife radiosurgery. The treatment of choice depends on the size of the tumor and the level of hearing in the affected ear. After gamma knife radiosurgery, there may be some neurological complications including headache, dizziness, motor or cranial nerve deficits, seizure, carotid artery stenosis, and increased intracranial pressure. Hydrocephalus is a rare complication of gamma knife radiosurgery for vestibular schwannoma. Conclusion Here, we report a case of normal pressure hydrocephalus after gamma knife radiosurgery in a patient with vestibular schwannoma.
