Ischaemic Changes of Different Anatomical Regions or Vascular Territories

Infarction involving the subcortical territory: Corona radiata infarct

The first scan shown is a non-contrast CT demonstrating a hypodense lesion at the right corona radiata arrow_1 (Figure 1). The next scan is a MRI (diffusion weighted imaging (DWI) sequence) from another patient, also with an infarct involving the corona radiata. The scan shows evidence of “restricted diffusion” over this region arrow_1 (Figure 2). Both of these patients presented with an acute onset of left hemiparesis, slurring of speech and left facial weakness of an upper motor neuron lesion pattern.
