Acoustic Neuroma

Symptoms

The signs and symptoms of acoustic neuroma develop from a tumor pressing on cranial nerves.

A small tumor may cause no signs and symptoms. But as the tumor grows, it may be more likely to cause symptoms, which may include:

• Hearing loss, usually gradual — although in some cases sudden — and occurring on only one side, or more pronounced on one side
• Ringing (tinnitus) in the affected ear
• Dizziness (vertigo)
• Loss of balance
• Facial numbness and weakness
