Acoustic neuroma
Alternate Names : Vestibular schwannoma, Tumor - acoustic, Cerebellopontine angle tumor, Angle tumor
Definition
An acoustic neuroma is a noncancerous (benign), often slow-growing tumor of the nerve that connects the ear to the brain. It is located behind the ear right under the brain.
Overview, Causes, & Risk Factors
An acoustic neuroma is believed to occur when there is a defect in a gene that normally prevents tumors from forming. The cause of the genetic defect is not known. However, acoustic neuroma is often linked with the genetic disorder neurofibromatosis type 2 (NF2). Acoustic neuromas are relatively uncommon.
