What are the signs of PML?
PML causes subacutely progressively (developing over weeks) neurological symptoms and findings that can be quite similar to an MS relapse. Some common symptoms of PML that are less often observed in MS included large visual field deficits and language deficits. PML does not create spinal cord problems so a “relapse” confined to the spinal cord (which is common in MS) is unlikely to be caused by PML.
