(Top) Series of 6 selected axial CECT images through the brain from inferior to superior are shown. Contrast in the lateral dural wall of

the cavernous sinus is seen on this section. (Middle) Section through the midbrain shows dura of the tentorium cerebelli with adjacent

basal veins of Rosenthal and lateral mesencephalic veins. (Bottom) Section through the foramen of Monro shows septal veins as they

curve around the pillars of the fornix behind the frontal horns of both lateral ventricles. The larger, midline enhancing area represents

choroid plexus as it is passing inferiorly from the lateral ventricles and forming the posterior border of the foramen of Monro. The

anterior border is formed by the pillars of the fornix.
