There is a perfusion defect in the right parietal lobe with a wedge shaped area of elevated TMAX (@Key Finding 1), diminished CBF (@Key Finding 2), and relatively preserved CBV (@Key Finding 3). This pattern would typically be expected with an infarct that has salvagable tissue and not much infarct core.

There is an associated right M2 branch occlusion with the occlusion at slice 367-368/510 on the CTA (@Key Finding 4). This matches nicely the location of the hyperdense M2 on the non-con head CT from Case 9a.

As a bonus, did you catch the incidental mass in the deep lobe of the left parotid gland (@Key Finding 5)? It turned out to be a Warthin tumor.
