Benign Paroxysmal Positional Vertigo vs Ménière Disease

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

Benign Paroxysmal Positional Vertigo and Ménière Disease 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.

Benign Paroxysmal Positional Vertigo vs Ménière Disease at a glance

  • Benign Paroxysmal Positional Vertigo: Brief positional vertigo from displaced otoconia in a semicircular canal; treat with canalith repositioning.
  • Ménière Disease: Inner-ear disorder of recurrent vertigo episodes, fluctuating low-frequency sensorineural hearing loss, tinnitus, and aural fullness.

Question 1NeurologyMedium
A 53-year-old woman has brief episodes of vertigo lasting seconds when rolling over in bed. Dix-Hallpike testing reproduces vertigo and nystagmus. Which of the following is the most appropriate treatment?
  • AOral antiviral therapy course
  • BIntratympanic gentamicin injection
  • CDaily oral diuretic therapy
  • DCanalith repositioning maneuver
Reveal answer & full explanation
Correct answer: D — Canalith repositioning maneuver
  • AOral antiviral therapy course
  • BIntratympanic gentamicin injection
  • CDaily oral diuretic therapy
  • DCanalith repositioning maneuver✓

Why Canalith repositioning maneuver is correct

  • Seconds-long positional vertigo with a positive Dix-Hallpike is benign paroxysmal positional vertigo from displaced otoconia.
  • The Epley canalith repositioning maneuver mechanically returns the debris to the utricle and is first-line.
  • It treats the mechanical cause directly without medication.

Why the others are wrong

  • Oral antiviral therapy course — Antivirals are sometimes used in vestibular neuritis, which causes sustained vertigo, not brief positional spells (wrong-vestibular-diagnosis trap).
  • Intratympanic gentamicin injection — Ablative gentamicin is reserved for refractory Ménière disease and would needlessly destroy vestibular function in BPPV (overtreatment trap).
  • Daily oral diuretic therapy — Diuretics target the endolymphatic hydrops of Ménière disease, not the otoconia of BPPV (vertigo-subtype trap).
Question 2NeurologyMedium
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.
