Abstract
Aim: The aim of the study was to present clinical neuro-otological symptoms in the case of early stage of the fourth ventricle tumor diagnosed finally on the base of MRI. Methods: The battery of otoneurological tests was performed to explain the clinical signs described in 1902 by L. Bruns. Tonal and speech audiometry, tympanometry, supralevel audiological tests (SISI, Carhartt), brain stem auditory evoked responses (BAEP), electro and videonystagmography (ENG-VNG), craniocorpography (CCG), Freyss芒�?�? stabilometry, cervical vestibular evoked myogenic potentials (cVEMP), somatosensory evoked potentials (SEP), visual evoked potentials (VEP) were analyzed. MRI finished the diagnosis. Results: The disturbances of visual-oculomotor, vestibular-oculomotor, vestibulo-spinal and other electrophysiological signs of the brainstem damage were noted. There were: Paresis of the sixth nerve unilaterally, prolonged latency of III-V waves on brain stem audiological responses (BERA), asymmetry of the fusion limit of optokinetic nystagmus (OPK), bilateral areflexia of the caloric and kinetic labyrinth reaction, abnormal Unterberger芒�?�?s test in craniocorpography (CCG) and the presence of gaze nystagmus. Conclusion: The study stressed the value of the wide and careful neuro-otological examination in Bruns syndrome. The electrophysiological diagnosis was finally confirmed by the MRI, showing the tumor (4�?�?2 mm) of fourth ventricle.Biography
