A vestibular schwannoma (VS), also called acoustic neuroma, is a benign tumor that develops on the vestibulocochlear nerve that passes from the inner ear to the brain. The tumor originates when Schwann cells that form the insulating myelin sheath on the nerve malfunction. Normally, Schwann cells function beneficially to protect the nerves which ...
Acoustic neuroma (vestibular schwannoma) – benign neoplasm of Schwann cells affecting the vestibulocochlear nerve; Meningioma – benign tumour of the pia and arachnoid mater; Ménière's disease – causes sensorineural hearing loss in the low frequency range (125 Hz to 1000 Hz).
Cellular schwannoma is a relatively rare variation. Cellular schwannoma is nearly exclusively made up of a fascicular proliferation of well-differentiated Schwann cells that are cytologically bland, missing Verocay bodies, and just slightly exhibiting Antoni B pattern growth (10% of the tumor area).
Neurofibromatosis type II, in which bilateral acoustic neuromas (tumors of the vestibulocochlear nerve or cranial nerve 8 (CN VIII) also known as schwannoma) develop, often leading to hearing loss. [16] Schwannomatosis, in which painful schwannomas develop on spinal and peripheral nerves. [17]
The most common cerebellopontine angle (CPA) tumor is a vestibular schwannoma affecting cranial nerve VIII (80%), followed by meningioma (10%). The cranial nerves affected are (from most common to least common) : VIII (cochlear component), VIII (vestibular component), V Acoustic neuroma/vestibular schwannoma
