Intracranial Venous System Overview

Superior sagittal sinus (SSS)

Inferior sagittal sinus (ISS)

Internal cerebral vein (ICV)

Straight sinus (SS)

Great cerebral vein (vein of Galen, VofG)

Transverse sinus (TS)

Superior/inferior petrosal sinuses (SPS/IPS)

Cavernous sinus (CS)

Internal jugular vein (IJV)

Basal vein of Rosenthal (BVR)

Superficial, deep middle cerebral veins (SMCV; DMCV)

Dural sinuses are large, endothelial-lined trabeculated venous channels encased within folds/reflections of dura that define, form their walls

Cerebral veins are thin-walled, valveless structures that cross subarachnoid space (SAS), pierce arachnoid/inner dura to enter dural venous sinus
