What causes tuberculous pericarditis?

Tuberculosis pericarditis is caused by infection of the pericardium with Mycobacterium tuberculosis.

When a patient is infected with Mycobacterium tuberculosis in the lungs, bronchi, bladder, etc., the pathogen spreads to the pericardium through blood circulation, direct spread, lymphatic circulation, etc., causing tuberculous pericarditis. If the patient is not vaccinated, immunity is low, etc., it is usually more likely to suffer from this disease.

Patients can be treated with isoniazid, rifampicin, ethambutol, etc. under the guidance of a doctor to control tuberculosis infection. If there is pericardial constriction, cardiac tamponade, etc., surgery may be required.
