Superior petrosal sinus
Introduction
The superior petrosal sinus, small and narrow, connects the cavernous with the transverse sinus.
It runs lateralward and backward, from the posterior end of the cavernous sinus, over the trigeminal nerve, and lies in the attached margin of the tentorium cerebelli and in the superior petrosal sulcus of the temporal bone; it joins the transverse sinus where the latter curves downward on the inner surface of the mastoid part of the temporal.
It receives some cerebellar and inferior cerebral veins, and veins from the tympanic cavity.
