There is variability in the severity of nodules caused by TB, and no generalizations can be made.
Some nodules caused by TB are not serious and can disappear on their own, while others are more serious and leave behind foci of fibrosis or calcification.
Tuberculosis nodules are specific granulomas formed on the basis of cellular immunity, consisting of epithelioid cells, Langerhans’ giant cells, and peripheral aggregates of lymphocytes and proliferative fibroblasts, with typical tuberculosis nodules having a caseous necrosis in the center.
Some nodules caused by tuberculosis are small in diameter and not serious, and in most cases, after standardized anti-tuberculosis treatment, the lesions can be completely absorbed without leaving sequelae.
However, some nodules caused by tuberculosis have a large number of nodules and a large diameter, and even if the tuberculosis is cured, the nodules are difficult to be completely absorbed and will leave different degrees of fibrosis or calcified foci.
Tuberculosis is a respiratory infectious disease caused by Mycobacterium tuberculosis infection, early detection, early diagnosis and early treatment is very critical.
Lung nodules formed by tuberculosis generally do not affect the patient’s lung function, and it is recommended to follow the doctor’s instructions to do regular review.
