COSTA, Izaias Pereira da et al. Polymyositis associated with lymphocytic arteritis of the central nervous system. Rev. Bras. Reumatol. [online]. 2010, vol.50, n.1, pp. 90-95. ISSN 0482-5004. http://dx.doi.org/10.1590/S0482-50042010000100009.
Central Nervous System (CNS) complications in idiopathic inflammatory myopathies are seldom reported. The authors describe the case of a 48-year old female with polymyositis and positive anti-Jo-1 autoantibody who, after five years of evolution, developed extensive CNS demyelinating injury associated with lymphocytic arteritis.
Keywords : polymyositis; central nervous system vasculitis; myositis-specific autoantibodies; anti-Jo-1.
