The sphenoparietal sinus is one of the dural venous sinuses and is located along the posteroinferior ridge of the lesser wing of the sphenoid bone. It drains into the cavernous sinus and receives tributaries from:
- superficial middle cerebral vein
- middle meningeal vein (frontal ramus)
- anterior temporal diploic vein
When these are large, the sphenoparietal sinus is also large.
