Inferior to the skull base, there is an intimo-medial flap in the right internal carotid artery which extends to the junction of the cervical and petrous segments. There is near occlusion of the vessel prior to skull base entry. Further superiorly, there is an area of what appears to be moderate to severe narrowing of the right ICA in the distal cavernous segment immediately adjacent to the anterior clinoid process, suspicious for an additional site of injury.
