An acoustic neuroma is a slow-growing tumor of the nerve that connects the ear to the brain. This nerve is called the vestibular cochlear nerve. It is behind the ear right under the brain.

An acoustic neuroma is not cancerous (benign), which means it does not spread to other parts of the body. However, it can damage several important nerves as it grows.

Vestibular schwannoma; Tumor - acoustic; Cerebellopontine angle tumor; Angle tumor

Acoustic neuromas have been linked with the genetic disorder neurofibromatosis type 2 (NF2).

Acoustic neuromas are relatively uncommon.
