brain, the most predictive MR imaging features, and the added value of comparison with …

Objective: Natalizumab is an effective treatment for patients with multiple sclerosis (MS) that
is associated with a risk of progressive multifocal leukoencephalopathy (PML) …

Progressive multifocal leucoencephalopathy has become a growing concern in natalizumab-
treated multiple sclerosis patients. Here, we describe a 35-year-old patient who was treated …

Progressive multifocal leukoencephalopathy (PML), first described on postmortem studies in
