Schwannomas are rare and slow growing tumours, arising from Schwann cells which provide myelin; less than 1 % of them degenerate into a malignant state. Although most studies are based on acoustic schwannomas, the majority of these tumours are non-vestibular and extracranial. Up to 45 % of them can be localised in ...
