"Additionally, similar imaging features, as well as similar pathophysiological processes, are seen in a variety of conditions where there is dysregulation of cerebral perfusion (e.g. posterior reversible encephalopathy syndrome (PRES), reversible vasoconstriction syndrome (RCVS), migraine, post-seizure encephalopathy, acute hypertensive encephalopathy, etc.) 10. Again, however, reserving cerebral hyperperfusion syndrome for this clinical scenario is preferred."

"T2/FLAIR: diffusely hyperintense in affected regions 3,4"

"Albeit less commonly, cerebral hyperperfusion syndrome can also develop after other procedures, such as angioplasty for MCA stenosis (ipsilateral syndrome), repair of aortic stenosis (bilateral syndrome), or direct revascularisation surgery for moyamoya disease/syndrome (ipsilateral syndrome) 5,6,13."
