title: Different Perfusion Patterns in a Patient with Acute Ischemic Stroke.
abstract: A 29-year-old male patient with aphasia and mild weakness of the right arm arrived at the emergency room 4 hours after symptom onset. The computed tomography perfusion showed a typical delay in the time-based maps in the left occipital lobe and another hyperperfused area in the left frontal lobe. The follow-up magnetic resonance imaging confirmed cortical ischemic lesions in both areas. This case shows that besides hypoperfusion, hyperperfusion can also be found in the first stages of acute stroke, and it is highly suggestive of established ischemic lesions.
