Ménière Disease vs Vestibular Neuritis and Labyrinthitis

Written & clinically reviewed by Ryan Busch, PA-C · Updated August 2026 · Report an error

Ménière Disease and Vestibular Neuritis and Labyrinthitis are easy to mix up on the boards. Here's a side-by-side comparison — presentation, workup, imaging, and first-line treatment — drawn from our full outlines.

Ménière Disease vs Vestibular Neuritis and Labyrinthitis at a glance

  • Ménière Disease: Inner-ear disorder of recurrent vertigo episodes, fluctuating low-frequency sensorineural hearing loss, tinnitus, and aural fullness.
  • Vestibular Neuritis and Labyrinthitis: Acute peripheral vestibulopathy from inflammation of the vestibular nerve (neuritis) or whole inner ear (labyrinthitis), producing prolonged vertigo.

Question 1NeurologyMedium
A 52-year-old woman reports four episodes over the past 6 months of spontaneous spinning vertigo, each lasting about 2 hours and accompanied by nausea, roaring tinnitus, and a sensation of fullness in her right ear. She notes that hearing in the right ear seems muffled during attacks. Between episodes her neurologic exam is normal. Pure-tone audiometry documents a fluctuating low-frequency sensorineural hearing loss confined to the right ear, with preserved word recognition. Which of the following is the most appropriate next diagnostic test?
  • AComputed tomography of the temporal bones
  • BGadolinium-enhanced MRI of the auditory canals
  • CVideonystagmography with bithermal caloric testing
  • DElectrocochleography of the affected right ear
Reveal answer & full explanation
Correct answer: B — Gadolinium-enhanced MRI of the auditory canals
  • AComputed tomography of the temporal bones
  • BGadolinium-enhanced MRI of the auditory canals✓
  • CVideonystagmography with bithermal caloric testing
  • DElectrocochleography of the affected right ear

Why Gadolinium-enhanced MRI of the auditory canals is correct

  • This vignette meets Barany/AAO-HNS criteria for Meniere disease (recurrent spontaneous vertigo 20 min to 12 h, fluctuating low-frequency unilateral sensorineural hearing loss, tinnitus, aural fullness).
  • Any patient with unilateral sensorineural hearing loss must be imaged to exclude a vestibular schwannoma and central pathology before Meniere disease is settled, so gadolinium-enhanced MRI of the internal auditory canals is the appropriate next step once audiometry confirms asymmetric loss.

Why the others are wrong

  • Computed tomography of the temporal bones — high-resolution CT resolves bony anatomy and is the study for superior semicircular canal dehiscence, otosclerosis, or cholesteatoma, but it cannot demonstrate the soft-tissue retrocochlear lesion that asymmetric sensorineural loss obligates you to exclude.
  • Videonystagmography with bithermal caloric testing — quantifies vestibular function and may show a unilateral caloric weakness, but this finding is non-discriminating among peripheral vestibulopathies and does not exclude a structural lesion.
  • Electrocochleography of the affected right ear — an elevated summating-potential to action-potential ratio supports endolymphatic hydrops, but it is neither sensitive nor specific enough to diagnose Meniere disease and does not exclude a schwannoma.
Question 2NeurologyMedium
A 42-year-old man presents with 2 days of severe, constant spinning vertigo, nausea, and gait instability that began after an upper respiratory infection 10 days earlier. He has no hearing loss or tinnitus. Examination shows spontaneous unidirectional horizontal-torsional nystagmus that is suppressed by visual fixation, an abnormal head impulse test with a catch-up saccade toward the left, and no skew deviation. There is no dysarthria, limb dysmetria, or focal weakness. He is diagnosed with vestibular neuritis. Which of the following best explains the findings?
  • AReactivation of latent virus within the superior vestibular nerve
  • BVertebrobasilar ischemia involving the inferior cerebellar territory
  • CEndolymphatic hydrops within the membranous labyrinth of the inner ear
  • DDislodged otoconia migrating into the posterior semicircular canal
Reveal answer & full explanation
Correct answer: A — Reactivation of latent virus within the superior vestibular nerve
  • AReactivation of latent virus within the superior vestibular nerve✓
  • BVertebrobasilar ischemia involving the inferior cerebellar territory
  • CEndolymphatic hydrops within the membranous labyrinth of the inner ear
  • DDislodged otoconia migrating into the posterior semicircular canal

Why Reactivation of latent virus within the superior vestibular nerve is correct

  • Vestibular neuritis is most often attributed to reactivation of latent HSV-1 within the vestibular (Scarpa's) ganglion, or post-infectious immune-mediated demyelination, of the superior vestibular nerve.
  • The superior division supplies the horizontal and anterior semicircular canals and the utricle; selective inflammation produces unilateral vestibular hypofunction with an abnormal head impulse and fast-phase nystagmus away from the affected ear.
  • The antecedent URI, sparing of hearing, peripheral HINTS pattern (abnormal impulse, unidirectional nystagmus, no skew), and absence of brainstem/cerebellar signs all fit neuritis rather than a central cause.

Why the others are wrong

  • Vertebrobasilar ischemia involving the inferior cerebellar territory — posterior circulation infarction is the dangerous mimic of acute vestibular syndrome, but it typically leaves the head impulse test NORMAL and produces direction-changing or vertical nystagmus or a skew deviation; this patient's abnormal head impulse, unidirectional fixation-suppressed nystagmus, and absent skew are the peripheral HINTS pattern.
  • Endolymphatic hydrops within the membranous labyrinth of the inner ear — this is the mechanism of Ménière disease, which causes recurrent vertigo lasting 20 min to 12 h with low-frequency hearing loss, tinnitus, and aural fullness, not a single prolonged event with preserved hearing.
  • Dislodged otoconia migrating into the posterior semicircular canal — this is the mechanism of BPPV, producing brief (seconds) positional vertigo with a positive Dix-Hallpike, not continuous vertigo lasting days.
