Sinus petrosus superior

The superior petrosal sinus is one of the dural venous sinuses located beneath the brain.

It receives blood from the cavernous sinus and passes backward and laterally to drain into the transverse sinus.

The sinus receives superior petrosal veins, some cerebellar veins, some inferior cerebral veins, and veins from the tympanic cavity.

They may be affected by arteriovenous malformation or arteriovenous fistula, usually treated with surgery.
