MRIPositive Diagnosis of Vestibular Neuritis Using Fluid Attenuated Inversion Recuperation (FLAIR) Sequence on a 1.5 Tesla

Positive Diagnosis of Vestibular Neuritis Using Fluid Attenuated Inversion Recuperation (FLAIR) Sequence, One Hour After Intravenous Gadolinium Injection, on a 1.5 Tesla

Our objective is to allow positive MRI diagnosis of vestibular neuritis by highlighting contrast enhancement of the vestibular nerve on the pathological side of the FLAIR sequence acquired 1h after intravenous gadolinium injection in patients with typical vestibular neuritis. At present, the diagnosis is based on a combination clinical examination / video-head impulse test, and no imaging examination allows the diagnosis to be positive.

Inclusion Criteria:

• Age 18-80 years
• Presence of a typical unilateral vestibular neuritis during the ENT examination with videonystagmography
• Subject having his agreement for the use of his medical data for research purposes.

Exclusion Criteria:

• Special clinical forms of the disease: doubtful or atypical forms, especially the presence of deafness
• Treatments and related interfering diseases, antecedents: antecedents of neuritis for controls, presence of vertigo, bilateral involvement
• Impossibility to give the subject information enlightened (subject in emergency situation, difficulties of understanding the subject, ...)
• Subject under the protection of justice
• Subject under guardianship or curatorship
