Since its introduction in 2009, the diagnostic criteria of radiologically isolated syndrome and its clinical relevance have been widely debated by neurologists and radiologists. The aim of the present study was to review the following: 1) historical evolution of radiologically isolated syndrome criteria, 2) clinical and imaging findings in adults and children with radiologically isolated syndrome, 3) imaging features of patients with radiologically isolated syndrome at high risk for conversion to MS, and 4) challenges and controversies for work-up, management, and therapeutic interventions of patients with radiologically isolated syndrome.CISclinically isolated syndromeDISdissemination in spaceDITdissemination in timeMAGNIMSMagnetic Resonance Imaging in MSRISradiologically isolated syndromeRRMSrelapsing-remitting multiple sclerosisCADASILcerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathyADEMacute disseminated encephalomyelitis ER -
