Increased texture in both lungs may be pneumoconiosis, or it may be caused by increased bronchial lung texture, lung tissue congestion, etc., which needs to be analyzed specifically. 1. Pneumoconiosis: prolonged contact with mineral dust will easily lead to diffuse fibrosis of lung tissue, causing hyperplasia of blood vessels and formation of pneumoconiosis, which is mostly manifested as scattered nodular shadows in both lungs and increased texture in both lungs in imaging examination. 2. Bronchogenic lung texture increase: lung texture is composed of bronchial tubes and pulmonary blood vessels, when there is inflammation, the exudation of blood vessels increases, and there will be an increase in bilateral lung texture. Mostly seen in bronchogenicity, its image features uneven thickness of lung texture, interspersed with deformed texture and small honeycomb shadow, commonly seen in chronic bronchitis, bronchiectasis and so on. 3. Congestion of lung tissue: If the patient has heart failure, due to the decline in the pumping function of the heart, it is easy to lead to stagnation of blood in the lungs, which leads to local congestion of the lung tissue and thickening of the capillaries, which can be manifested as an increase in the texture of both lungs. Increased bilateral lung texture can also be seen in other diseases, it is recommended to go to a specialized hospital, after clarifying the cause of the disease, under the guidance of the doctor for further examination and treatment.
