acoustic schwannoma

vestibular schwannoma

a benign but life-threatening tumor arising from Schwann cells, usually of the vestibular division of the eighth cranial nerve in early stage; produces hearing loss, tinnitus, and vestibular disturbances and in late stages cerebellar, brainstem, and other cranial nerve signs and increased intracranial pressure. Synonym(s): acoustic neurinoma, acoustic neuroma, acoustic schwannoma, acoustic tumor, cerebellopontine angle tumor, eighth nerve tumor

acoustic schwannoma

A non-malignant but hardly benign tumour of the cells of the sheath of Schwann on the acoustic nerve. The tumour causes one-sided deafness and tinnitus and eventually expands inwards into the cranial cavity to occupy the space between the cerebellum and the pons of the brainstem (the cerebello-pontine angle). Surgical approach is difficult but untreated growing tumours are liable to prove fatal. Also known as acoustic neuroma or vestibular schwannoma. (Theodor Schwann, 1810–82, German anatomist).
