Evolution of stroke on CT and MRI. Day 1: NCHCT demonstrates obscure left insular cortex. No abnormal lesion is identified on T2-weighted imaging. DWI and ADC images show restricted diffusion in the left insular cortex and left lenticular nucleus, consistent with acute infarction (open arrow). PWI abnormalities in the left MCA territory. The PWI/DWI mismatch is thought to represent ischemic penumbra (arrow). Day 2: NCHCT demonstrates hypodense left lenticular nucleus and left insula (arrow), consistent with acute infarction. The corresponding lesion is identified on T2-weighted MRI and DWI (open arrow) with an additional hyperintense lesion in the left temporal cortex (open curve arrow). The abnormality on PWI (arrow) is mostly resolved. Week 2: Subacute infarct in the left lentiform nucleus (arrow). Month 2: The images show a chronic infarct in the left lentiform nucleus (arrow). #Stroke #CVA #MRI #Interpretation #Progression #Timeline #Neurology #Radiology #Findings #Evolution
