A 74-year-old male presented with a three-month history of cough and asthma. 18F-FDG PET/CT imaging revealed tuberculous pericarditis, pulmonary tuberculosis, and tuberculous lymphadenitis. NGS identified Mycobacterium tuberculosis complex sequences in the patient’s bronchoalveolar lavage fluid. Images A-B demonstrated pericardial lamellar thickening with diffuse 18F-FDG uptake; images C-D illustrated mediastinal tuberculous lymphadenitis with high 18F-FDG uptake; images E-F highlighted supraclavicular tuberculous lymphadenitis. All lesions are indicated by red arrows
