Vestibular schwannoma

A noncancerous tumor on the main nerve leading from the inner ear to the brain.

Overview

A vestibular schwannoma usually grows slowly or not at all. However, in a few cases, it may grow rapidly and become large enough to press against the brain and interfere with vital functions.

Symptoms

Pressure from the tumor can cause hearing loss, ringing in the ear, and unsteadiness.

Treatments

The tumor may just require monitoring. When treatment is needed, it may include radiation or surgical removal.
