Female, 78 years old, with muscle weakness, assess for stroke. Patchy foci of diffusion restriction are demonstrated within the left MCA territory, specifically involving the corona radiata and the posterior insula. Extensive patchy periventricular T2 hyperintensities are noted bilaterally as well as more vague signal abnormality in the pons. No evidence of significant generalized mass effect is seen. No intracranial hemorrhage or any abnormal extra axial fluid collections are detected. No pathologic intracranial enhancement is seen. Ventricular size and morphology are within normal limits.
