internal cerebral vein

The dorsal layer covers internal cerebral veins and fixes them to the surrounding tela choroidea.

The internal cerebral veins are formed by the union of the thalamostriate vein and the choroid vein at the interventricular foramen.

It also contains the right and left internal cerebral veins (which drain the choroid plexuses) at its roof (the two veins unite to form the great cerebral vein).

The cerebral veins are divisible into external and internal (internal cerebral veins) groups according to the outer surfaces or the inner parts of the hemispheres they drain into.

The superior cerebellar veins pass partly forward and medialward, across the superior vermis, to end in the straight sinus and the internal cerebral veins, partly lateralward to the transverse and superior petrosal sinuses.

The hypothesis of a spontaneous origin in the current case of SP is supported by no evidence of associated anomalies, such as cerebral aneurysmal venous malformations, systemic angiomas, venous angioma dural malformation, internal cerebral vein aneurysm, and cavernous hemangiomas.

The basal vein passes backward around the cerebral peduncle, and ends in the internal cerebral vein (vein of Galen); it receives tributaries from the interpeduncular fossa, the inferior horn of the lateral ventricle, the hippocampal gyrus, and the mid-brain.
