The main deep cerebral veins are (Fig. 2.25):
• Great vein (of Galen)
• Left and right basal vein (of Rosenthal)
• Left and right internal cerebral veins
2.3.3 Vascular Variants
The human cerebrovasculature is highly variable and vascular variants have been
extensively studied (see, e.g. [6, 10, 13, 22]). Variations exist in terms of origin,
location, shape, size, course, branching patterns, as well as surrounding vessels
and structures. The knowledge of cerebrovascular variants is central in diagnosis,
treatment, and medical education.
Some main variants of the circle of Willis synthesised in 3D are shown in
Fig. 2.26 (more 3D vascular variants are presented in [70]).
