A 67-year-old man with AD on anti-Aβ monoclonal antibody trial. T2 FLAIR image shows hyperintensity in the parasagittal left frontal lobe (oval in a), with no evidence of hyperintensity on DWI (b), and associated subcortical microhemorrhages (oval in c). None of these abnormalities were present prior to receiving antibody therapy (d–f), consistent with ARIA with edema and hemorrhage. Arterial spin labeling demonstrates hypoperfusion to the parietal and frontal lobes (g), with corresponding diffuse cortical uptake on florbetapir PET/CT typical of AD (h)
