Slightly blurred texture in both lungs generally suggests a mild infection of the lower respiratory bronchi, which can manifest clinically as a mild cough and cough. Chronic bronchitis with infection can also be considered if the patient has a long history of smoking. If pediatric imaging suggests slightly blurred texture in both lungs, one needs to be alert to the possibility of bronchopneumonia. Physical examination may reveal thickened breath sounds in both lungs, and limited wet rales may also be heard, and blood tests may suggest signs of lung infection such as increased total white blood cells and neutrophils. Therefore, an increase in the texture of both lungs that is slightly blurred is usually indicative of a milder condition and tends to be a bronchial infection. If present in young children one also needs to be alert to respiratory infections inducing heart failure and aggravating the condition. Therefore, a slightly blurred texture in both lungs is usually indicative of bronchial pathology, and clinical treatment with anti-infection and Chinese herbal medicine can control the disease as soon as possible.
