A 65-year-old man with Takayasu arteritis in a stable condition was admitted to our hospital because of rapid progressive dementia. Brain FLAIR/T2-weighted magnetic resonance images revealed high signal intensity in the diffuse subcortical white matter. John Cunningham virus (JCV) genome in cerebrospinal fluid was detected by polymerase chain reaction.

[Characteristics of group A streptococci isolated from children with non-suppurative complication or severe infection].
