abstract = "We described a case of John Cunningham virusinduced granule cell neuronopathy in a 36-year-old patient with multiple sclerosis (MS) who was treated with natalizumab for 6 years. This patient developed progressive cerebellar syndrome. Within 6 months, 3 successive MRIs with DWI
disclosed rapidly progressive cerebellar atrophy with cortical cerebellar signal intensity abnormalities, including high signal intensity on DWI with mildly decreased ADC values. This report highlighted the importance of detecting the early MR features of John Cunningham virus neuronopathy
in a patient with MS who was treated with natalizumab and who had recent-onset cerebellar syndrome.",
