CT venogram reconstructon shows the typical locations of various sphenoidal group sinuses in the middle cranial fossa. CT venogram reconstructon shows the typical locations of various sphenoidal group sinuses in the middle cranial fossa. The sinus is found along the lesser wing of sphenoid (long arrow). The sphenobasal sinus (arrowheads) and sphenopetrosal sinuses (asterisk) travel medially and laterally on the middle cranial fossa floor, respectively. They also have connections to the emissary veins of the foramen rotundum (solid arrow) and foramen ovale (open arrow). Z.-S. Shi et al.
