Neurotologic and functional MRI findings in a patient with bilateral profound deafness having Brown-Vialetto-Van Leare syndrome.

چکیده
INTRODUCTION We report the first findings of functional magnetic resonance imaging of the auditory cortex in a young woman with a bilateral cochleovestibular deficit as first manifestation of Brown-Vialetto-Van Leare syndrome. The patient had no open speech discrimination, even with hearing aids, and is depending on lip reading for communication. METHODS To evaluate the possible efficiency of a cochlear implantation, we investigated hemodynamic responses within the central auditory pathways using an auditory functional magnetic resonance imaging paradigm. RESULTS Blood oxygen level-dependent correlates were detected bilaterally along the auditory pathways after exposure to intermittent clicking tone stimulation at 2 kHz. CONCLUSION These results suggest integrity of the central auditory pathways and represent a positive argument to propose a cochlear implantation with the aim to restore hearing.

Brown-Vialetto-Van Laere syndrome (BVVLS) is a rare type of motor neuron disease, characterized by bilateral deafness, and multiple cranial nerve involvement. The disease is more frequent in females, but rapid deterioration was attributed to male gender or early onset. Herein, we report a man with BVVLS who had a longer than expected interval between onset of deafness and other motor symptoms t...

Brown-Vialetto-Van Laere syndrome is a rare neurological disorder with a variable age at onset and clinical course. The key features are progressive ponto-bulbar palsy and bilateral sensorineural deafness. A complex neurological phenotype with a mixed picture of upper and lower motor neuron involvement reminiscent of amyotrophic lateral sclerosis evolves with disease progression. We identified ...

The syndrome described by Brown(l) Vialetto(2) and Van Laere(3) is a rare, often familial, characterized by bilateral nerve deafness followed or accompanied by involvement of various motor cranial nerves, e.g., 7th and 9th to 12th, rarely 3rd, 5th and 6th. On rare occasions, there may also be involvement of spinal motor nerves and less commonly of upper motor neurons. The onset of the disease i...
