  • Figure 1
    Brain MRI
     

    FLAIR Shows symmetric subtle linear hypointensity in the putaminal nuclei.

     
    Area of Interest: Neuroradiology brain; Imaging Technique: MR; Procedure: Education; Special Focus: Dementia;

    T2WI Does not show significant findings.

    Brain MRI - SWI
     

    SWI Shows severe low signal intensity of the putaminal nuclei (compared to globus pallidus).
