Acoustic Neuroma Symptoms & Diagnosis

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 Herbert Wertheim 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.
