What does the lung line shadow mean?

In life, many men like to smoke very much. However, a lot of smoking can easily cause lung infection. Although the inflammation can be eliminated through drug treatment, it is easy to leave scars in the lungs. In this case, a CT scan will show lung cords. Therefore, it is best to reduce the number of smoking as much as possible and take measures to prevent respiratory diseases. So what does lung cords mean?

First, what does the linear shadow in the lung mean ? If there are linear patchy shadows in the lungs during reexamination, it is very likely a remnant of pneumonia. If there are no abnormal symptoms, no treatment is needed for the time being. It is more appropriate to observe first. If the child has a fever, cough, sputum and breathing, it may be a relapse of pneumonia, and medication must be used again. The child needs to be hospitalized as soon as possible to avoid worsening of the disease. In addition, a cardiac color Doppler ultrasound examination is needed to rule out the occurrence of congenital heart disease, and then targeted treatment is given.

Second, tuberculosis . The cellulose strips have their own common sites, generally located in the bilateral lung apices and the dorsal segments of the lower lobes, and are often accompanied by other basic lesions, such as exudative lesions, cavities, calcifications, proliferative nodules, etc. Fibrosis can pull the hilum of the lung into a weeping willow shape, which can reduce the volume of the lung tissue and shift the mediastinum to the affected side. Nonspecific inflammation of the lungs. Chest X-rays can show clear signs of inflammation and abscesses. After the infection is controlled, the inflammation of the original lesions is absorbed. If the absorption is incomplete, localized lung streak-like shadows will remain. Sometimes, incomplete absorption of chronic nonspecific inflammation in the lungs may also leave scar fibrous cords.

What do the linear shadows in the lungs mean ? Localized atelectasis is common in patients who have been bedridden for a long time, and is often manifested as linear shadows in the area of ​​aspiration (behind the lower lung in the supine position), which may appear as subpleural lines or other forms, and may be accompanied by small flakes of ground-glass exudates, which are manifestations of aspiration pneumonia. They may change with body position and are all located in the low-hanging area close to the ground. Some elderly and frail patients may have coarse horizontal linear shadows in the lower lung field on their chest X-rays, which are manifestations of discoid atelectasis.
