RESUMEN
PURPOSE: We report a case of pyogenic arthritis of the shoulder secondary to infective endocarditis. MATERIALS AND METHODS: A 70 year-old male who had suffered from pyogenic arthritis of the left shoulder secondary to infective endocarditis was treated with artificial valvuloplasty, arthroscopic synovectomy and drainage. RESULTS: Infection was cured and the patient achieved a good functional outcome. CONCLUSION: Pyogenic arthritis of the shoulder is rarely associated with infective endocarditis. However, if the symptoms are misdiagnosed as musculoskeletal symptoms associated with infective endocarditis, serious complications may arise. As such, musculoskeletal symptoms associated with infective endocarditis should be paid careful attention.
