The great cerebral vein is one of the large blood vessels in the skull draining the cerebrum of the brain.

[2] This comes from the inferior side of the posterior end of the corpus callosum and empties ie similarities, there are also differences between these two types of veins in the brain.

The superficial veins at the dorsal parts of the hemispheres run upward and medially and empty into the large superior sagittal sinus in the upper margin of the falx cerebri.

They pierce the arachnoid mater and the meningeal layer in the dura and drain into the cranial dural venous sinuses.

In its absence, the veins from the diencephalon and the basal ganglia drain laterally into the transverse sinus instead of conjoining in the midline through the Galenic drainage system.

[9] Patients may present with consciousness problems, headaches, nausea, visual defects, fatigue, disturbance of eye movements and pupillary reflexes, or coma.
