RESUMO

In the present study 20 human brains were used to verify the presence of a small body projecting into the floor of the straight sinus at its junction with the great cerebral vein. The elevation could be identified at the anterior end of the floor of the straight sinus with an empty cavity underlying it. Histologically, the elevation was found to consist of interwoven bundles of collagen fibres covered by vascular endothelium continuous with that of the straight sinus. The importance of such an elevation in the regulation of blood flow from the great cerebral vein to the straight sinus is discussed from a hydrodynamic point of view.
