PML is a concerning adverse event of natalizumab, as PML can cause substantial morbidity or mortality in MS patients. This article discusses the management of PML in patients with MS, the prevalence of John Cunningham virus reactivation during treatment with natalizumab, as well as the use of T2*-weighted high-resolution MRI to detect PML
