Area of abnormal signal (low on T1 and high on T2/FLAIR) with high diffusion signal at right lentiform nucleus compatible with acute ischemic stroke.
High signal foci in T2 and flair sequences at subcortical and periventricular white matter of both cerebral hemispheres depicts chronic microvascular ischemia.
Case Discussion
The lateral lenticulostriate arteries arise from the proximal middle cerebral artery (MCA), usually from the M1 segment, more rarely from the postbifurcation or M2 segment. They supply the lateral portion of the putamen and external capsule as well as the upper internal capsule.
