Under normal circumstances, tuberculous pleurisy usually does not leave sequelae as long as it is treated in a timely manner and the medication is administered in a standardized and adequate manner. However, if the patient does not receive timely and effective treatment, sequelae may remain, as follows: 1. Pleural hypertrophy, the pleural mucosa will thicken under the stimulation of inflammation such as Mycobacterium tuberculosis, thus causing pleural hypertrophy. 2. Pleural adhesions, because patients with tuberculous pleurisy will have pleural effusion, which contains a large amount of protein and fibrin, and if the pleural fluid is not extracted in a timely manner, it may lead to pleural adhesions. 3. 3. encapsulated pleural effusion, which usually occurs after the pleural adhesions are formed, resulting in encapsulated pleural effusion, and in severe cases, patients may also develop pleural calcification and thoracic collapse and other sequelae.
