JF The Journal of Rheumatology JO J Rheumatol FD The Journal of Rheumatology SP 207 OP 211 VO 28 IS 1 A1 M Regan A1 U Haque A1 M Pomper A1 C Pardo A1 J Stone YR 2001 UL http://www.jrheum.org/content/28/1/207.abstract AB We describe a 47-year-old woman with refractory dermatomyositis (DM) who developed progressive cognitive dysfunction. Magnetic resonance imaging showed a large cerebral infarction, and the diagnosis of central nervous system (CNS) vasculitis was confirmed by both angiogram and brain biopsy. Her DM and CNS vasculitis responded promptly to the institution of daily cyclophosphamide, and her previously refractory disease entered remission.
