Case ReportsBacterial endocarditis and septic arthritis presenting as polymyalgia rheumatica.
We describe a case of enterococcus endocarditis in a 74-year-old woman with hypercholesterolemia, porcine aortic valve, and osteoarthritis. She presented with the abrupt onset of severe back pain, proximal myalgia, and left knee synovitis, associated with an anemia and marked elevation of ESR. She was misdiagnosed as having polymyalgia rheumatica until both the synovial fluid and blood cultures grew enterococcus. ⋯ However, one-third of all cases of bacterial endocarditis have musculoskeletal symptoms. These include backache, arthritis of the peripheral joints, and diffuse myalgia and arthralgia. Unexplained rheumatic complaints should alert us to the possibility of bacterial endocarditis.
