Tuberculous pleurisy is divided into dry pleurisy and exudative pleurisy and is a common cause of pleural hypertrophy.
Dry pleurisy often results in limited pleural thickening or adhesions.
Exudative pleurisy produces a large amount of pleural fluid, which has a large amount of fibrin proteins deposited in the pleura, and encapsulated effusion and extensive pleural thickening can form during the absorption of pleural fluid.
