The inferior petrosal sinus is situated in the inferior petrosal sulcus formed by the junction of the petrous part of the temporal with the basilar part of the occipital.

It begins in the postero-inferior part of the cavernous sinus, and, passing through the anterior part of the jugular foramen, ends in the superior bulb of the internal jugular vein.

The inferior petrosal sinus receives the internal auditory veins and also veins from the medulla oblongata, pons, and under surface of the cerebellum.
