Initial electrocardiogram showed sinus tachycardia and diffuse concaved ST elevation. Transthoracic echocardiogram revealed pericardial effusion with tamponade physiology. CT thorax was notable for dense left lung consolidation with pleural effusion. Emergent pericardiocentesis and percutaneous balloon pericardiotomy were performed which successfully drained 500\u2009mL of purulent pericardial fluid. A left chest tube was placed and revealed a large volume of empyema. Both pericardial and pleural fluid cultures yielded similar strains of <jats:italic>Streptococcus anginosus<\/jats:italic>. The patient was initially treated with empiric broad-spectrum intravenous antibiotics which were eventually de-escalated to intravenous ceftriaxone based on microbiology culture and sensitivity. Unfortunately, the patient developed pulseless electrical activity arrest on day 10 of intensive care unit stay and expired despite cardiopulmonary resuscitation.<\/jats:p>","DOI":"10.1136\/bcr-2022-249871","type":"journal-article","created":{"date-parts":[[2022,6,22]],"date-time":"2022-06-22T12:02:45Z","timestamp":1655899365000},"page":"e249871","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":5,"title":["<i>Streptococcus anginosus<\/i> purulent pericarditis with cardiac tamponade presenting as a complication of postobstructive pneumonia"],"prefix":"10.1136","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-7809-2473","authenticated-orcid":false,"given":"Si Yuan","family":"Khor","sequence":"first","affiliation":[{"name":"Department of Medicine, Michigan State University, East Lansing, Michigan, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Abdul-Fatawu","family":"Osman","sequence":"additional","affiliation":[{"name":"Department of Medicine, Michigan State University, East Lansing, Michigan, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Priyal","family":"Agarwal","sequence":"additional","affiliation":[{"name":"Department of Medicine, Michigan State University, East Lansing, Michigan, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sandeep","family":"Banga","sequence":"additional","affiliation":[{"name":"Department of Cardiovascular Disease, Michigan State University, East Lansing, Michigan, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"239","published-online":{"date-parts":[[2022,6,22]]},"reference":[{"key":"2025082701512155000_15.6.e249871.1","doi-asserted-by":"publisher","DOI":"10.1016\/0735-1097(93)90592-O"},{"key":"2025082701512155000_15.6.e249871.2","doi-asserted-by":"publisher","DOI":"10.2165\/00129784-200505020-00004"},{"key":"2025082701512155000_15.6.e249871.3","doi-asserted-by":"publisher","DOI":"10.1056\/NEJMcp1404070"},{"key":"2025082701512155000_15.6.e249871.4","doi-asserted-by":"publisher","DOI":"10.1016\/0002-9343(77)90150-4"},{"key":"2025082701512155000_15.6.e249871.5","doi-asserted-by":"publisher","DOI":"10.1016\/S0002-9343(00)00459-9"},{"key":"2025082701512155000_15.6.e249871.6","doi-asserted-by":"crossref","unstructured":"Maves RC , Tripp MS , Franzos T , et al .
