Primary purulent pericarditis by Streptococcus pneumoniae. Case-report and literature review Background: Purulent pericarditis has become a rare clinical entity since the onset of antimicrobial therapy and has a poor outcome in the majority of cases. Case-report: A healthy 3 month-old patient admitted with dyspnea, pallor and anorexia, developing cardiogenic shock due to cardiac tamponade. Chest X-ray showed cardiomegaly. He required mechanical ventilation, volume resuscitation and vasoactive drugs. Echocardiogram showed a large pericardial effusion, CT scan ruled out lung and mediastinal infection. Pericardial drainage was performed and Vancomycin plus Ceftriaxone were initiated, with a positive blood culture for Penicillin-sensitive Streptococcus pneumoniae. The evolution was favourable after surgical drainage and controlling the infection. No extraperdicardial infection was found. He received 3 weeks of antibiotic therapy. Immunological studies were normal. Conclusion: Primary purulent pericarditis is uncommon, so early detection and treatment of this life-threatening condition may lead to a good outcome.
