- Marked progressive attenuation of the distal ICAs; namely the right cavernous segment and the supra-clinoid segment of either ICA, together with their bifurcations, and both A1 and M1 segments of the ACA and MCA respectively as well as attenuation of the proximal circle of willis.
- Hypertrophied lenticulostriate and thalamostriate arteries with multiple basal ganglia collaterals. Contrast-enhanced CT shows enhancing dots within the basal ganglia and abnormal enhancing network of vessels at the base of the brain.
- Fairly patent distal anterior cerebral and middle cerebral arteries on both sides.
- Persistent fetal origin of both PCAs with normal calibre as well as the basilar artery and scanned distal vertebral arteries.
- No evidence of cerebral aneurysms or arterio-venous malformations.
- Normal appearance of the dural venous sinuses and cerebral veins.
- Global brain atrophy with reduced volume of the right cerebral hemisphere.
