Abstract
BACKGROUND: Spontaneous intracranial hypotension may be associated with neuro-otological symptoms that might mimic Menière's disease. CASE PRESENTATION: We report the case of a 53-year-old male presenting bi-frontal headache with recurrent spells of vertigo, left fluctuating hearing loss, and tinnitus. Dedicated brain and inner ear Magnetic Resonance Imaging, including a post-contrast 4 hours delayed FLAIR sequence, revealed typical signs of spontaneous intracranial hypotension associated with endolymphatic hydrops involving the left saccule and cochlea. CONCLUSIONS: Audio vestibular manifestations mimicking Menière's disease in spontaneous intracranial hypotension could be explained by endolymphatic hydrops, which can be detected using dedicated magnetic resonance imaging sequences.
