A Case of Isolated Central Nervous System Vasculitis in an Elderly Patient

A 83 year old Italian woman, with unremarkable family history, was admitted in 2013 to a Neurology Ward for lumbar pain and progressive motor impairment of right lower limb. The only remarkable event in her past history had been a clinical diagnosis of Rheumatoid Arthritis (RA) 20 years earlier, not confirmed by laboratory tests and radiological imaging. The neurological examination showed an isolated mild right lower limb paresis, 4/5 on the MRC scale (medical research council muscle scale), no sensory defi cit and preserved symmetrical tendon refl exes.
