We describe an 80\u2010year\u2010old man presenting with recurrent fever and weakness, found to have a large pericardial effusion with tamponade physiology requiring emergent pericardial window drainage. Pericardial fluid analysis demonstrated an exudative, lymphocyte\u2010predominant effusion with elevated lactate dehydrogenase and low glucose levels, but initial acid\u2010fast bacillus smear, histopathology, and sputum studies were negative.

This case underscores the importance of considering TBP in patients with unexplained pericardial effusion, particularly in those with epidemiologic risk factors, and highlights the diagnostic value of Xpert MTB\/RIF as a rapid and highly specific molecular assay that can expedite diagnosis and improve clinical outcomes.\n                  <\/jats:p>","DOI":"10.1155\/crdi\/2518518","type":"journal-article","created":{"date-parts":[[2026,7,20]],"date-time":"2026-07-20T11:33:22Z","timestamp":1784547202000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Unmasking Tuberculosis Pericarditis: The Role of Xpert MTB\/RIF in Early Diagnosis and Treatment\u2014A Case Report"],"prefix":"10.1155","volume":"2026","author":[{"ORCID":"https:\/\/orcid.org\/0009-0001-5315-3794","authenticated-orcid":false,"given":"Saumya","family":"Nanda","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tharun","family":"Shyam","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Prabal","family":"K.
