-
Nono haemorrhage or signs of acute infarction. No large vessel occlusion. -
Severesevere complex right CCA bifurcation/proximal ICA atheromatous plaque causing high-grade stenosis and near-complete occlusion. -
Singlesingle right vertebral artery supplies the basilar artery, with a high-grade atheromatous stenosis of V4. -
Perfusionperfusion colour maps demonstrate increased time parameters reflecting penumbra in the right cerebral hemisphere due to the high-grade stenosis of the ICA. These changes could also be secondary to seizure but there was no indication of this in the clinical presentation. No core infarct identified. -
Oldold right ACA infarction.
The patient was not suitable for IV thrombolysis.
