ntracranial Venous System Overview

Septal vein

Vein of Galen

Straight sinus

Apex of tentorium

Vein of Galen

Internal cerebral veins (paired)

Straight sinus

Precentral cerebellar vein

Thalamostriate veins

Falx cerebri

Straight sinus

Choroid plexus, veins

Superior vermian cistern

Pineal gland (calcified)

Anterior caudate vein

(Top) Scan at the level of the upper foramen of Monro. The vein of Galen, a U-shaped structure, is seen here with its anterior and

posterior segments seen as 2 contrast-filled "dots" that curve above the pineal gland and under the corpus callosum splenium. (Middle)

Section through the internal cerebral veins, paired paramedian structures, shows their extent from the thalamostriate tributaries

anteriorly to the vein of Galen posteriorly. (Bottom) Scan through the upper ventricles and tentorial apex is depicted. Anterior caudate

veins are subependymal tributaries of the thalamostriate veins. The septal and thalamostriate veins join to form the internal cerebral

veins.
