Thickening and blurring of the texture of both lungs is an imaging manifestation of acute and chronic bronchitis during an exacerbation. Under normal circumstances, the texture of both lungs is clear and natural, but in patients who have smoked for a long time or have had a bronchitis attack, the texture of both lungs is thickened and increased. However, if the texture of both lungs is thickened and accompanied by blurring, it is necessary to consider that the ordinary chronic state is accompanied by an acute infection, for example, the patient will have a cough, sputum, coughing yellow sputum or white sputum, accompanied by chest tightness, shortness of breath, and even fever. If the blood count is elevated, a lower respiratory tract infection, such as bronchitis or an acute attack of chronic bronchitis, may be considered. Therefore, thickening and blurring of the lung texture is mainly indicative of an infection in both lungs, especially in the lower respiratory tract, and suggests that the doctor may give Chinese or Western medication.
