Venous phase cone beam axial MP4
Stillshot views — superficial sylvian (superficial middle cerebral) veins (arrow) drain into a short sphenoparietal / laterocavernous sinus (dashed arrows) and into the cavernous sinus. There is sometimes a kind of narrowing in this area (arrowhead) where sinus preservation is particularly important.
