Large pure intracranial vagal schwannoma.

We report a patient with a large, pure intracranial vagal schwannoma, compressing the medulla who presented with essential hypertension. Based on this and on previous cases, we suggest that a differentiation of pure intracranial schwannomas (subtype A1) from intracranial schwannomas with some extension in the jugular foramen (type A) should be used.
