Both lungs are slightly thickened. What do you mean?

The texture of both lungs is slightly rough, which means that the texture of both lungs is more disordered and rough than that of normal lung during chest X-ray or chest CT examination. At this time, it needs to be analyzed in combination with clinical manifestations such as cough, expectoration, fever and shortness of breath. If there are the above symptoms, it is considered to be caused by bronchitis and bronchopneumonia. If there are no clinical symptoms, it is found during physical examination. The patient usually has a history of smoking or exposure to dust at work. It may be caused by this reason. The thickening of lung markings can also be seen in the elderly or obese normal people.
