was changed:
The basilar venous plexus lies between the endosteal and visceralmeningeal layers of the dura on the inner surface of the clivus and connects numerous regional venous structures:
- superiorly
- cavernous sinuses (superolaterally)
- superior petrosal sinuses (superolaterally)
- intercavernous sinuses (superiorly)
- laterally: inferior petrosal sinuses
- anteriorly: clival diploic veins 3
- inferiorly
The plexus can be prominent and can appear to erode the posterior surface of the clivus mimicking a clival mass 2.
