Vestibular schwannoma is a benign tumor that develops depending on the schwanne sheath of the vestibular nerve. We report the case of a patient with upper vestibular nerve schwanoma treated by radiosurgery Gamma Knife®. This is a 53-year-old patient with no particular history who presents progressive left hearing loss for three years with homolateral tinnitus and recurrent vertigo, without facial paralysis, headache or other neurological symptoms. She has a normal otoscopy with left perception deafness and a positive Halmagy test on the left. The tonal audiometry reveals a left severe hearing loss. A videonystagmography reveals a left deficit syndrome. In the Video-Halmagy impulse test, we have a superior and lateral left semi-circular canals dysfunction. Magnetic resonance imaging reveals a 7*5 mm stage 1 a vestibular schwannoma. The patient received a gammaknife by radiosurgery. The outcomes are favorable. However, the patient had left unilateral cophose and post-therapeutic headaches without facial nerve paralysis. Vestibular schwannoma is a benign tumor who can cause a vital dysfunction by its localisation. Therapeutic management must ensure tumor control without being aggressive.
