Pleural thickening, due to the stimulation of pleura by Mycobacterium tuberculosis and its metabolites, pleural thickening will occur. 2. Pleural adhesion, tuberculous pleurisy may appear pleural effusion, pleural fluid contains a large amount of fibrin, if the pleural fluid is not withdrawn in time, it may lead to pleural adhesion. 3. encapsulated pleural effusion, mostly seen in exudative pleurisy, if not treated in time, it may lead to severe inflammatory exudation, localized mechanization and calcification, forming encapsulated pleural effusion.
