What are the symptoms of acoustic neuroma?

Symptoms of acoustic neuroma occur when tumors grow large enough to press on neighboring nerves, blood vessels and brain tissue.

Common symptoms include:

  • Hearing loss in one ear (often happens slowly but can be sudden)
  • Vertigo (loss of balance with spinning dizziness)
  • Ringing in one ear
  • Numb or weak facial muscles
  • Headaches
  • Double vision
  • Nausea and vomiting

How is acoustic neuroma diagnosed?

Your doctor will likely conduct a hearing exam after assessing your symptoms and conducting a physical exam. You will then undergo an MRI test to confirm a diagnosis of acoustic neuroma.

Specialty neuroradiologists at Miami Cancer Institute use the latest MRI technology to create detailed images of the brain and tumors affecting the brain. A contrast dye is injected into a vein to create a clearer picture of your brain and the tumor. You feel no pain during the exam, but you may be given a sedative before the procedure to help you relax.
