Immune reconstitution inflammatory syndrome (IRIS) appears after the withdrawal of certain drugs such as natalizumab (NTZ) or fingolimod. The development of PML-IRIS after NTZ treatment has been described, and its diagnosis is made by clinical and radiological criteria and the determination of the John Cunningham virus in CSF. We present a clinical case of a patient with MS who, after the withdrawal of fingolimod, developed PML-IRIS despite sustained lymphopenia. This is important for pharmacovigilance purposes, not only for NTZ but also for alternative drugs used in MS treatment.}, publisher = {S.
