An extended computed tomography perfusion protocol in a patient with petechial hemorrhage in the ischemic/infarcted brain following tissue plasminogen activator. A: The unenhanced CT shows loss of the gray white interface in the right insula; B: PS map with ROI over the affected territory and unaffected territory on the contralateral side. PS values are 1.38 and 2.95 mL/100 per minute on the unaffected and affected sides, respectively; C: Follow-up imaging the next day showed petechial hemorrhage in the infarcted tissue. ROI: Region of interest; CT: Computed tomography; PS: Permeability-surface area product maps.
