Abstract
A 52-year-old woman with myalgia, anti-aminoacyl tRNA synthetase, anti-SS-A/Ro52 antibody positivity, and elevated creatine kinase levels was admitted to our hospital. She was diagnosed with Sjögren's disease (SjD) complicated by polymyositis (PM). No chest symptoms were observed. Although her electrocardiogram and echocardiogram findings were normal, cardiac magnetic resonance imaging (CMRI) revealed myocardial edema and fibrosis with late gadolinium enhancement, elevated extracellular volume, and elevated T2 values. After treatment with prednisolone, the myalgia and CMRI abnormalities improved. This case suggests that CMRI may be useful for the detection and treatment of subclinical myocardial damage in patients with SjD complicated by PM.
