From a right groin approach ( 5 F sheath), bilateral CCA, ICA and ECA angiography was performed.
Distortion of the supraclinoid right ICA remains evident ( narrowing now approximately 20-30%).
The tumour receives its blood supply from right ICA and MCA branches, with no significant ECA supply. No significant supply from the left ICA or ECA.
Incidental note is made of a sessile 2.3mm right ICA bifurcation aneurysm.
