Cerebral veins (diagram)

Case contributed by Frank Gaillard
Annotated image

Cerebral veins annotated on a CT venogram.  

Note: the anatomy in the region labeled superior vermian vein is a little ambiguous and demonstrates a recognized variant, namely the precentral vein and the superior vermian vein joining before joining the vein of Galen as a single trunk. The alternative anatomy is that these two veins drain separately, the precentral vein more anteriorly. 

In the CTA grey-scale image, the more correct term for this single trunk is the superior cerebellar vein (rather than the superior vermian vein).
