Pulmonary textural disturbances are usually indicated by imaging in acute and chronic bronchitis with infection, and a general chest radiograph indicating pulmonary textural disturbances indicates the presence of infection. Increased lung texture is seen in the stable stage of bronchitis and chronic bronchitis, and once it is accompanied by disorder, it is indicative of infection, which may result in cough, sputum, chest tightness, and even fever. Pulmonary textural disorders can also be seen in patients who have been smoking for a long time. Therefore, the increased lung texture disorder does not belong to the category of pneumonia, tuberculosis, or lung tumor, but is a manifestation of common bronchitis, so it is not necessary to be too nervous.
