Rt & Lt images: Axial CT images of brain show subtle effacement of the cortical
sulci on the left along with some focal hypodensity within the cortex.
All images: Axial post-contrast CT images one day later demonstrate
hypodense lesion in the cerebral cortex of Lt parietal region. Prominent
serpiginous enhancement in the adjacent sulci represents dilated MCA
arteries due to collateral flow and vasomotor deregulation.
Key words: stroke vascular
