Dural Tentorial Fistula of Bernasconi-Cassinari Artery, Two Case Reports: Supratentorial and Infratentorial

We report two rare and infrequent cases, one of a patient with a Cognard type V tentorial dural fistula diagnosed at the beginning as a trunk glioma in a patient with gait disturbance. And another with a Guillian Barré syndrome with tetraparesis secondary to a tentorial dural arteriovenous fistula.
