A-D demonstrated fast protocol to exclude recent ischemia or bleeding, with patency of large intracranial vessels and without significant changes in structural images (Diffusion, Gradient-Echo and FLAIR). E-H with the reconstructions of the perfusion study and highlighting the important increase in time to the plateau (TTP -figure G) and mean transit time (MTT -figure F), with no changes of the other parameters. I-M with the perfusion control study and characterizing the regression of the previously evidenced changes.

... describe the case of a 16-year-old adolescent with diagnostic previous of migraine without and with aura (only sensory), who presented with aphasia of speech, associated with severe retroorbital pain and frontal headache on the left, associated with nausea, photo and phonophobia. He was admitted to the emergency room with suspected stroke and was submitted to magnetic resonance perfusion imaging of the brain (Figure 1). After ruling out suspected cerebral ischemia, treatment with symptomatic medications was performed, progressing to improvement of symptoms after about 2 hours. ...
