Bilateral tentorial sinus drainage of the basal vein (of Rosenthal).

We report a case of bilateral collateral tentorial venous sinus drainage of the basal vein (of Rosenthal) (BV). The observation was made on a corrosion cast of the cerebral venous system obtained from a fresh cadaver. Radiographic correlation was obtained by performing standard X-ray imaging of the corrosion cast. Embryologic and clinical considerations are discussed. Copyright 2003 Wiley-Liss, Inc.
