    MR images obtained in 1994
     

    An axial proton density weighted image (taken in 1994) showing a subtle increase in the white matter signal in the left frontotemporal region.

     
    Area of Interest: unknown; Imaging Technique: MR images from 1994;

    An axial T2W image (taken in 1994) showing a mild atrophy of the left cerebral hemisphere.

    MR images obtained in 1999

    A post-gadolinium axial T1W image (taken in 1999) showing no enhancement but only atrophy of the left temporal region.

     
    Area of Interest: unknown; Imaging Technique: MR images from 1999;

    MR images obtained in 2001
     

    An axial T2W image (taken in 2001) showing white matter hyperintensities with a progressive atrophy of the left hemisphere during an episode of clinical relapse.

     
    Area of Interest: unknown; Imaging Technique: MR images from 2001;

    An axial FLAIR image (taken in 2001) showing white matter hyperintensities with a progressive atrophy of the left hemisphere during an episode of clinical relapse.

    MR images obtained in 2003

    An axial T2W image (taken in 2003) showing prominent atrophy. The right hemisphere is characteristically spared.

    MRS

    An MR spectroscopy image showing decreased NAA and raised myoinositol peak. Atrophy usually causes significant artefacts on spectroscopic imaging.
