The disappearance of tuberculosis lesions mainly depends on anti-tuberculosis treatment. In most patients with tuberculosis, the lesions can be absorbed with regular anti-tuberculosis treatment. For a small number of patients, even after regular anti-tuberculosis treatment and sufficient course of treatment, there may be fibrous nodule-like lesions in the lungs. These lesions are fine, as long as the tuberculosis is cured, these lesions are scar tissue and have no special effects, as long as they are reviewed regularly. There are also some patients who have tuberculosis spheres or old lesions when the lung lesions are found, which usually do not require treatment and can be reviewed regularly on chest X-ray.
