Vestibular nerve schwannoma, treated with gamma knife and diagnosed after transitory ischemic attack in posterior cerebral vascularisation

Abstract

A case of a patient is shown, who was admitted for neurological exploration, with clinical manifestations of the cerebrovascular accident in the posterior circulation (TIA V-B vascularisation). In accordance with diagnostic protocol, an endocranial CT was performed. The results of the brain CT indicated an existence of an alteration in the right pontocerebellar angle area, which was subsequently diagnosed as a n. vestibularis schwannoma in an NMR examination. After a neurosurgical deliberation, the patient was treated with a gamma knife. After this surgery, which was done in a local anesthesia, the patient s condition was well and he was discharged. Control examinations have shown minor difficulties during the stimulation of the left ear auditive structures. Control examinations involving NMR showed no signs of recidivate focal findings.
