Increased lung texture is mostly seen in the following conditions: First, chronic bronchitis. Chronic bronchitis can present with increased texture in both lungs, often with cough, coughing, chest tightness, shortness of breath, and other symptoms, often recurrent. Second, bronchiectasis. Patients with bronchiectasis may have increased lung texture, and some patients may have a combination of cystic and columnar shadows. Third, cardiac insufficiency. Patients with cardiac insufficiency have heart failure and pulmonary stasis, and may have increased texture in both lungs. If there is only an increase in the texture of both lungs and the patient does not have obvious symptoms such as coughing, coughing, chest tightness, shortness of breath, etc., it can be observed and reviewed regularly.
