Tumors which arise from the cells that form the protective sheath around the body's nerve fibers. They are usually benign and are surgically removed when possible. One of the more common forms of schwannoma affects the eighth cranial nerve, which contains nerve cells important for balance and hearing. Also known as vestibular schwannomas or acoustic neuromas, these tumors may grow on one or both sides of the brain.
