The CTA study demonstrates poor opacification of intracranial vasculature due to raised intracranial pressure. There is opacification of the right internal carotid artery and reduced opacification of the narrow calibre right M1. Minimal vascular opacification beyond this point on the right.
There is poor opacification of the left ICA from beyond the petrous segment of this vessel with markedly reduced opacification of the left MCA.
Co-dominant vertebral arteries. Very narrow calibre basilar artery. The cervical portions of the ICA opacify normally.
