Figure 6

82-year-old man presented with left hemiparesis. (a) Axial unenhanced CT images 2 hours after stroke show a hyperdense right MCA (thick arrow) and loss of the insular ribbon (thin arrow). Patient received intravenous thrombolysis after the CT. (b) Axial unenhanced CT images 3 days later show petechial hemorrhages in the striatocapsular area and a hematoma within the right lentiform nucleus, consistent with hemorrhagic transformation after thrombolysis. Stage HI d1 [1]. (c) CT perfusion image shows a large area of delayed mean transit time on the right. (d) CT angiogram shows truncation of mid M1 segment of the right middle cerebral artery (arrow).
