Sphenoparietal sinus
Sinus sphenoparietalis
- Eponym: Sinus of Breschet
Definition
The sphenoparietal sinus (sinus of Breschet), is a small dural venous sinus which courses along the under surface of the small wing of the sphenoid.
The sphenoparietal sinus collects venous blood from the anterior temporal lobe and receives tributaries from vessels including the superficial Sylvian, middle meningeal, and anterior temporal diploic veins to then drain into the cavernous sinus
The sphenoparietal sinus is implicated in various clinical pathologies, specifically arteriovenous fistulas and venous sinus thrombosis.
