Progressive Multifocal Leukoencephalopathy in a Multiple Sclerosis Patient Diagnosed after Switching from Natalizumab to Fingolimod

<div>Patterns of Gadolinium enhancement on 7 T VIBE images. A maximum intensity projection map of a 7 T T1 weighted Gadolinium enhanced volumetric interpolated brain examination ((a), VIBE) and an exemplary VIBE image (b) are displayed. PML-suspicious punctate Gadolinium enhancing lesions are clearly visible (circles). Ring-enhancing lesions (e.g., arrows) suggestive of MS lesions are delineated.</div>
