Synonyms: acoustic neurilemoma, acoustic neurinoma, vestibular schwannoma
Acoustic neuromas are tumours of the vestibulocochlear nerve (eighth cranial nerve), arising from the Schwann cells of the nerve sheath. Most arise from the vestibular portion and only a few arise from the cochlear (auditory) division. They are typically benign and slow-growing, but can cause symptoms through mass effect and pressure on local structures, eventually becoming life-threatening. Patterns of growth can vary and a small number may grow rapidly (doubling size in six months). Considering the possibility can enable earlier diagnosis, can increase management options and may decrease morbidity.
