Fig 2.

T2-weighted (A), FLAIR (B), and isotropic DWI (C) of a unilateral lesion in a patient with an acute or chronic presentation of worsening right-sided weakness. There are 2 T2-weighted hyperintense lesions involving the genu and posterior limb of the internal capsule (white arrow) and posterolateral putamen (black arrow). Both T2-weighted (A) and FLAIR (B) images reveal lesions of differing age with an anteromedial well-defined encephalomalacic cavity and a posterolateral lesion. The isotropic image (C) confirms a new focal area of infarction within the lateral lenticulostriate artery territory (black arrow) as an area of reduced diffusion.
