Superior view of three-dimensional contrast-enhanced magnetic resonance venogram of three different individuals showing draining veins to anterior third of superior sagittal sinus and its various branching patterns. The posterior limit of anterior third of superior sagittal sinus has been marked with yellow arrows. (a) No branching of draining veins at anterior third of superior sagittal sinus. (b) Twin branching (red arrow) of draining veins at anterior third of superior sagittal sinus. (c) Multiple branching (red arrow) of draining vein at anterior third of superior sagittal sinus
