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

Abstract

Vestibular schwannoma (VS) is a benign tumor that grows in Schwann cells of the eighth cranial nerve, and it can be treated by surgical removal or stereotactic radiosurgery including gamma knife surgery. Stereotactic radiosurgery for VS was first attempted in 1969 and has been one of the most active treatments in the last 40 years. The main side effects include facial paralysis, hearing loss, trigeminal neuralgia, and hemifacial spasm [1]. In addition, hydrocephalus is a potential concomitant disease [2-4]. In this article, we report a case of normal pressure hydrocephalus (NPH) Normal pressure hydrocephalus after gamma knife radiosurgery in a patient with vestibular schwannoma
