Acoustic Neuroma (Vestibular Schwannoma)
Greene J, Al-Dhahir MA. Acoustic Neuroma (Vestibular Schwannoma). StatPearls 2020; .
Acoustic neuroma is also called vestibular schwannoma (VS), acoustic neurinoma, vestibular neuroma or acoustic neurofibroma. These are tumors that evolve from the Schwann cell sheath and can be either intracranial or extra-axial. They usually occur adjacent to the cochlear and vestibular nerves and most often arise from the inferior division of the latter. Anatomically, acoustic neuroma tends to occupy the cerebellopontine angle. About 5-10% of cerebellopontine angle (CPA) tumors are meningiomas and may occur elsewhere in the brain. Bilateral acoustic neuromas tend to be exclusively found in individuals with type 2 neurofibromatosis.
