Abstract

Vestibular schwannomas, more commonly known as acoustic neuromas (ANs), are benign, extra-axial tumours that originate from the schwann cells of the vestibular branches of the vestibulocochlear nerve (cranial nerve [CN] VIII). ANs account for 8–10 % of all intracranial tumours and 80 % of those involving the cerebellopontine angle (CPA). The incidence of ANs has been estimated to be 10–15 per one million people annually [1, 2]; the widespread and increasing use of MRI may lead to a more accurate, higher incidence because of the higher detection rate. The diagnosis of an AN is usually made in adults between the ages of 40–60 years, and the vast majority of these cases are sporadic, resulting from a somatic mutation. ANs are rarely diagnosed in teenagers in whom the tumour is associated with neurofibromatosis type 2 (NF2).
