Quick Facts
The internal cerebral veins are a pair of deep cerebral veins that are formed from the union of the thalamostriate vein and the choroidal vein near the interventricular foramen. Running posteriorly between the tela choroidea of the third ventricle and beneath the splenium of the corpus callosum the internal cerebral veins drain the deep aspects of the cerebral hemisphere and are eventually joined by the Basal veins to form the great cerebral Vein.
