Acoustic Neuroma

Typically a peripheral cause of Vertigo|| If acoustic neuroma is very larger, it can put pressure on Cerebellopontine Angle (CPA), in which case it causes central vertigo

Your Path

  • Acoustic Neuroma


  • Unilateral
  • Tinnitus
  • Sub-acute and progressive hearing loss (sensorineural)
  • Sometimes assoc w/dizziness

Physical Exam Findings

  • Decreased ability to hear whispered words, rubbed fingers thru affected ear(s)
  • If patient hums, sounds louder in normal ear
  • External canal and TM should be normal (assuming no co-existing conductive loss)
  • Weber w/512hz tuning fork lateralizes to normal ear; Rinne indicates air conduction better than bone
