title: Purulent pericarditis, an uncommon entity in modern practice: a case report.
abstract: We report an 82-year-old female with pneumococcal pneumonia. Antimicrobial therapy was started in an early stage of the disease. On the 10th day of admission she developed peripheral pitting oedema with elevated jugular venous pressure and a drop in blood pressure. Her electrocardiogram showed sinus tachycardia and concave upward ST-segment elevation in almost all leads. A transthoracic two-dimensional echocardiogram revealed a large circumferential pericardial effusion, with diastolic collapse of the right atrium and a mitral inflow pattern that suggested cardiac tamponade. Emergency pericardiocentesis was performed, releasing 600 cc of thick green purulent material, followed by good haemodynamic recovery. The haemodynamic state, pneumonic infiltrate and inflammatory parameters responded gradually to antimicrobial therapy and the patient recovered and was discharged after six weeks. We conclude that even susceptible strains ofStreptococcus pneumoniain a patient with no predisposing factors may still cause purulent pericarditis, even in the era of adequate antibiotic therapy.
