- Marginal venous sinus (foramen magnum)
The marginal sinus is a dural venous sinus and runs along the inner margin of foramen magnum. It has numerous communications with regional venous structures 1-2:
- anteriorly: basilar venous plexus
- posteriorly: occipital sinus
- laterally
- sigmoid sinus
- veins of the hypoglossal canal
- inferiorly: vertebral venous plexus
The vertebral arteries usually pierce the sinus as they enter the intracranial cavity 1.
