Figure 2

Top row, left: Admission CT showing hypoattenuation of the right lentiform nucleus and insular cortex as well as slight swelling of cortical sulci in the right frontoparietal region. Top row, the third and the fourth pictures: The perfusion CT on admission, with flow and mean transit time CT showing a broad perfusion deficit in the right MCA region. Top row, the second picture: The volume chart shows only a small deficit in the right MCA region, consistent with the presence of a large ischemic penumbra in the cortical cerebral tissue. Middle row: The follow-up brain MRI showing the presence of a limited subcortical infarct on the distal region of the right lentiform nucleus and corona radiata. Signs of only a subtle cortical infarction are seen. From left to right: FLAIR MRI, T2-diffusion-weighted MRI, apparent diffusion coefficient. Middle row, right: The persistence of the right MCA occlusion on the follow up MRA. Bottom row: Day 2 CT showed that the extent of the subcortical infarct was substantially smaller than that of the perfusion deficit found in the CT perfusion brain scan obtained on admission.
