Findings of a representative case. Cerebral infarction is observed in the right lenticulostriate artery (LSA) area of a 72-year-old woman. Diffusion-weighted MRI scanning was performed 11 days after ischemic stroke infarction experienced by the patient. Axial diffusion-weighted imaging (DWI) reveals an acute infarction, classified as a small-artery disease in the right paraventricular corona radiata (a), with a decreased axial apparent diffusion coefficient (ADC) map (b). Imaging of the cerebral peduncle and internal capsule demonstrates hyperintensity on the axial and coronal DWI (c and e), as well as hypo-intensity on the axial and coronal ADC map (d and f), in the descending cortical tract. Multiplanar reconstruction generated coronal DWI and ADC map section images (e and f). MRI: magnetic resonance imaging
