What is tuberculous pericarditis?

Tuberculosis pericarditis is generally associated with lymphatic dissemination of Mycobacterium tuberculosis, direct spread of local infection, and hematogenous dissemination of Mycobacterium tuberculosis.

1. Lymphangiogenous dissemination of Mycobacterium tuberculosis

If there is infection of Mycobacterium tuberculosis in the trachea, bronchus, mediastinum, or hilar lymph nodes, the bacteria can retrograde through the lymphatic vessels to the pericardium to form tuberculous pericarditis.

2. Direct spread of local infection When

caseous lesions appear in the lungs of tuberculosis patients, they can spread directly to the pericardium, resulting in tuberculous pericarditis.

3. hematogenous dissemination of Mycobacterium tuberculosis If

infection occurs in the urinary system, bones, etc., the virus can spread to the pericardium through blood circulation, causing tuberculous pericarditis.
