Differentiating between Hemorrhagic Infarct and Parenchymal Intracerebral Hemorrhage
Figure 14
24-year-old woman presented with dense right hemiparesis and seizure. (a) Initial axial diffusion weighted MR images show an extensive area of diffusion restriction in the left basal ganglia and insular cortex. There is also a small area of restricted diffusion in the left corona radiate (arrow). Staphylococcus was grown from her peripheral blood culture, and she was treated for bacterial endocarditis. (b) Axial unenhanced CT images 3 weeks later show extensive hemorrhage within the area of the initial infarction. Stage IIH d2 [1]. (c) MR angiogram shows occlusion of the left middle cerebral artery, consistent with hemorrhagic transformation of the initial stroke.
