Diffusion restriction consistent with ischaemia involves almost the entirety of the pons, the entire left posterior cerebral artery territory, and a moderate-sized wedge-shaped portion of the right posterior inferior cerebellar artery territory. Smaller foci of diffusion restriction elsewhere in the cerebellar hemispheres compatible with embolic infarction.
The TOF MRI demonstrates flow along the length of the basilar artery with a 3mm segment of persistent basilar artery stenosis at the site of angioplasty.
