Primary pyomyositis is an infective condition mainly involving the skeletal muscles. Various cardiac complications reported are acute bacterial endocarditis, pyogenic pericarditis, pancarditis and, very rarely, pyopericardium presenting as cardiac tamponade. We report a case of 15-year-old boy presenting with complaints of fever, progressive shortness of breath and retrosternal pleuritic chest pain. He also complained of painful swellings of left arm, left side of neck and left thigh extending up to the knee joint. Ultrasonography showed collections in the: bilateral sternocleidomastoid; subclavius; left thigh muscles; and left knee joint. Echocardiography showed evidence of cardiac tamponade. He underwent emergent pericardiocentesis and frank pus was drained. Pus culture grew Methicillin resistant Staphylococcous aureus. With drainage and the appropriate antibiotics, he improved.

The first data of Lyme carditis, a relatively rare manifestation of Lyme disease, were published in eighties of the last century. Clinical manifestations include syncope, light-headedness, fainting, shortness of breath, palpitations, and/or chest pain. Atrioventricular (AV) electrical block of varying severity presents the most common conduction disorder in Lyme carditis. Although is usually mild, AV block can fluctuates rapidly and progress from a prolonged P-R interval to a His-Purkinje block within minutes to hours and days. Rarely, Lyme disease may be the cause of endocarditis, while some studies and reports, based on serological and/or molecular investigations, have suggested possible influence of Borrelia burgdorferi on degenerative cardiac valvular disease. Myocarditis, pericarditis, pancarditis, dilated cardiomyopathy, and heart failure have also been described as possible manifestations of Lyme carditis. The clinical course of Lyme carditis is generally mild, short term, and in most cases, completely reversible after adequate antibiotic treatment.

A 77-year-old man with a past medical history of myelodysplastic syndrome, coronary artery disease, hypertension, and chronic atrial fibrillation presented at the hematology outpatient clinic with progressive shortness of breath, weakness, and chest and back pain. Echocardiography was performed and the patient was diagnosed with severe pericardial effusion near the right ventricle. Pericardial drainage was performed. Erysipelothrix rhusiopathiae was isolated from the pericardial fluid. Complications of respiratory and renal failure developed during follow-up. The clinical and laboratory findings of vegetation on the tricuspid valve, pericardial effusion, and atrial fibrillation with a low heart rate suggested possible pancarditis. A multidisciplinary treatment approach with the cardiology and infectious disease departments was critical to successful management of this case.
