Acoustic Neuroma


A benign tumor that grows from schwann cells of the vestibular nerve. Also called vestibular schwannomas, these growths commonly lead to progressive hearing loss, ringing in the ear (tinnitus), and balance problems. They often grow first in the auditory canal and then expand to compress the brain. Treatment options include surgical resection, stereotactic radiosurgery, or fractionated radiation therapy. The tumors can be slow growing and in some patients are simply observed. When tumors are present on both the right and left sides of the brain, a condition called neurofibromatosis type 2 exists.
