A 73\u2010year\u2010old man presented with fever and cough. Chest imaging revealed pneumonia and bilateral pleural effusions developed during antibiotic treatment. The right effusion was neutrophil\u2010dominant, consistent with parapneumonic effusion, while the left was lymphocyte\u2010dominant, suggesting Dressler syndrome triggered by pneumonia\u2010induced systemic inflammation. Both effusions were bloody, an appearance possibly exacerbated by the concomitant use of a direct oral anticoagulant and aspirin. The left effusion recurred months later but significantly improved following ibuprofen treatment, supporting an immune\u2010mediated aetiology. This case highlights that bilateral effusions can arise from different aetiologies and that pneumonia\u2010induced inflammation may trigger a latent immune response related to prior cardiac surgery.<\/jats:p>","DOI":"10.1002\/rcr2.70764","type":"journal-article","created":{"date-parts":[[2026,9,16]],"date-time":"2026-09-16T12:34:49Z","timestamp":1789562089000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Bilateral Bloody Pleural Effusions With Discordant Cellular Patterns: A Case of Concurrent Parapneumonic Effusion and Dressler Syndrome"],"prefix":"10.1002","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0009-0006-1883-4718","authenticated-orcid":false,"given":"Yoshitsugu","family":"Narumi","sequence":"first","affiliation":[{"name":"Department of Internal Medicine and Pulmonary Medicine Seikei\u2010kai Chiba Medical Center  Chiba Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Susumu","family":"Hoshino","sequence":"additional","affiliation":[{"name":"Department of Internal Medicine and Pulmonary Medicine Seikei\u2010kai Chiba Medical Center  Chiba Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Midori","family":"Yamakawa","sequence":"additional","affiliation":[{"name":"Department of Internal Medicine and Pulmonary Medicine Seikei\u2010kai Chiba Medical Center  Chiba Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yoshiko","family":"Amano","sequence":"additional","affiliation":[{"name":"Department of Internal Medicine and Pulmonary Medicine Seikei\u2010kai Chiba Medical Center  Chiba Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2026,9,16]]},"reference":[{"key":"e_1_2_10_2_1","doi-asserted-by":"publisher","DOI":"10.1056\/NEJMra1403503"},{"key":"e_1_2_10_3_1","volume-title":"StatPearls [Internet]","author":"Shebl E.","year":"2025"},{"key":"e_1_2_10_4_1","doi-asserted-by":"publisher","DOI":"10.1001\/archinte.160.17.2665"},{"key":"e_1_2_10_5_1","doi-asserted-by":"publisher","DOI":"10.5606\/tgkdc.dergisi.2019.15090"},{"key":"e_1_2_10_6_1","doi-asserted-by":"publisher","DOI":"10.1002\/jhm.981"},{"key":"e_1_2_10_7_1","doi-asserted-by":"publisher","DOI":"10.1093\/eurheartj\/ehv318"},{"key":"e_1_2_10_8_1","doi-asserted-by":"publisher","DOI":"10.1097\/01.smj.0000203657.48512.63"},{"key":"e_1_2_10_9_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.ijcard.2012.09.052"},{"key":"e_1_2_10_10_1","doi-asserted-by":"publisher","DOI":"10.1136\/bcr\u20102018\u2010228877"},{"key":"e_1_2_10_11_1","doi-asserted-by":"publisher","DOI":"10.1097\/MCP.0000000000000383"},{"key":"e_1_2_10_12_1","doi-asserted-by":"publisher","DOI":"10.1186\/s12890\u2010021\u201001743\u20109"}],"container-title":["Respirology Case Reports"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1002\/rcr2.70764","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/full-xml\/10.1002\/rcr2.70764","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1002\/rcr2.70764","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,9,25]],"date-time":"2026-09-25T01:54:47Z","timestamp":1790301287000},"score":1,"resource":{"primary":{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/10.1002\/rcr2.70764"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2026,9]]},"references-count":11,"journal-issue":{"issue":"9","published-print":{"date-parts":[[2026,9]]}},"alternative-id":["10.1002\/rcr2.70764"],"URL":"https:\/\/doi.org\/10.1002\/rcr2.70764","archive":["Portico"],"relation":{},"ISSN":["2051-3380","2051-3380"],"issn-type":[{"value":"2051-3380","type":"print"},{"value":"2051-3380","type":"electronic"}],"subject":[],"published":{"date-parts":[[2026,9]]},"assertion":[{"value":"2026-05-10","order":0,"name":"received","label":"Received","group":{"name":"publication_history","label":"Publication History"}},{"value":"2026-09-08","order":2,"name":"accepted","label":"Accepted","group":{"name":"publication_history","label":"Publication History"}},{"value":"2026-09-16","order":3,"name":"published","label":"Published","group":{"name":"publication_history","label":"Publication History"}}],"article-number":"e70764"}}
