 Examination is limited due to patient motion artifact and inability to complete all sequences. There is an area of diffusion restriction centered in the left basal ganglia and left caudate nucleus that also involves a portion of the corona radiata, corresponding to area of hypoattenuation seen on prior CT. This area is also associated with T2 hyperintensity. There are other scattered punctate foci of T2 hyperintensity in the periventricular and deep white matter and left thalamus. Again seen is an area of volume loss in the right occipital lobe, in the area of hypoattenuation on CT.The ventricles and sulci are within normal limits. The cisterns remain patent. There is no midline shift or significant mass effect. No extra-axial fluid collection is identified.Normal flow-voids are grossly demonstrated in the visualized major intracranial vascular structures. The midline structures and craniocervical junction are within normal limits.
1.Limited examination demonstrating an acute to subacute infarct centered in the left basal ganglia.2.Foci of T2 hyperintensity in the periventricular, deep white matter, and left thalamus likely represent mild chronic small vessel ischemic disease.
