Magnetic Resonance Imaging in Vestibular Neuritis

Abstract
|
|
|
Acute vestibular neuritis is a discrete degenerative neuropathy of the vestibular nerve trunks. The etiology for the loss of the vestibular function is postulated to be a viral neuritis like Bell's palsy. The purpose of this study is to ascertain
viral
etiology using magnetic resonance imaging (MRI) with Gadolinium enhancement. Seventeen patients with acute vestibular neuritis were evaluated in a prospective study by MRI. Twenty patients with Bell's palsy were evaluated as a control. None of
patients
with acute vestibular neuritis exhibited contrast enhancement of labyrinth, vestibulocochlear nerve, or vestibular ganglion. In contrast, all of Bell's palsy demonstrated contrast enhancement of facial nerve. The observed difference betweeen
Bell's
palsy and acute vestibular neuritis may be due to their arteriovenous structure of the nerve. However the futher studies should be required.
