Abstract
- Here, we report a case in which the rapid diagnosis of tuberculous pericarditis was made using Mycobacterium tuberculosis (MTB)-specific interferon-gamma release assay on peripheral blood and pericardial effusion. Acid-fast bacilli staining, mycobacterial culture, and nucleic acid amplification targeting MTB using pericardial fluid were negative. However, elevated adenosine deaminase (ADA) activity in pericardial fluid and interferon-gamma release assay positivity in both pericardial fluid and peripheral blood indicated the presence of tuberculous pericarditis. After anti-tuberculous and steroid treatment, the patient's clinical symptoms improved, and pericardial effusion has not reoccurred.
