Inclusive Anatomy
Structure:
The great cerebral vein is a short, midline venous trunk located deep within the brain.[1] It is formed posteriorly by the union of the paired internal cerebral veins, just inferior to the splenium of the corpus callosum and superior to the pineal gland.[1]
The great cerebral vein is a major component of the deep cerebral venous system, which drains the internal structures of the brain, including the thalami, basal nuclei, choroid plexus, and deep white matter.[1,2] The vein courses posteriorly and superiorly, passing beneath the splenium of the corpus callosum, before terminating in the straight sinus.[1]
Like other intracranial veins, the great cerebral vein has thin walls and lacks valves.[1] Its mean length is approximately 0.9–1.0 cm, reflecting its role as a short but critical collecting channel.[2]

Function:
The primary function of the great cerebral vein is to drain venous blood from the deep cerebral structures into the dural venous system.[1,3] After formation from the internal cerebral veins, it conveys blood to the straight sinus, which subsequently drains into the confluence of sinuses.[1]
Because it serves as the principal outflow pathway of the deep cerebral venous system, obstruction or malformation of the great cerebral vein can lead to significant neurological consequences, including hydrocephalus, venous congestion, and hemorrhage.[3]
