basilar venous plexus

The basilar venous plexus lies between the endosteal and visceral 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
• inferiorly
  • vertebral venous plexus
  • marginal sinus 

The plexus can be prominent and can appear to erode the posterior surface of the clivus mimicking a clival mass .
