Recurrent myositis triggered by infections: A case report

Introduction: Recurrent myositis triggered by infections is unusual, with only one other case reporting two attacks described in the literature. Case presentation: We report the case of a 24-year-old Caucasian woman with recurrent myositis triggered by sore throat, respiratory and urinary tract infections, over the past 18 years, up to four times a year. Myositis of this frequency and duration, apparently triggered by infections, has not been reported previously. Conclusion: We believe that this case adds to the understanding of myositis associated with infections being a triggered autoimmune response, and postulate that the pathogenesis in our patient is a non-specific immune response to a range of different precipitants, both bacterial and viral. © 2008 Wong et al; licensee BioMed Central Ltd.
