Acoustic neuroma - Overview

Alternative Names

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

Definition of Acoustic neuroma:

An acoustic neuroma is a noncancerous (benign), often slow-growing tumor of the nerve that connects the ear to the brain.

Causes, incidence, and risk factors:

These tumors are thought 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, but they are one of the most common types of brain tumors.

The tumor is usually found at the base of the brain.
