Few fibrous nodules in the lungs are usually foci left after the recovery of tuberculosis, but they may also be pulmonary nodules, which need to be judged in the light of the actual situation.
1. Tuberculosis: Tuberculosis is a disease caused by bacterial infection, after the onset of the patient will produce lung inflammation, and cause lung tissue damage, serious and even destroy the structure of the lungs, and the patient in the treatment, although the condition of tuberculosis has been recovered, but the condition of the lungs will continue to exist, necrotic tissue is newborn fibrous tissue wrapped to the inner lungs will produce a small fibrous The necrotic tissue is wrapped by the newborn fibrous tissue, which will result in a few fibrous foci in the lung.
2. Lung nodules: Lung nodules have many causes, such as long-term smoking, inhalation of dust, etc., after the onset of lung granulomas, diseased tissues exist for a long time without treatment, with the repair of lung tissues, granulomas are wrapped by the tissue inside the formation of pulmonary fibrotic sclerosis foci.
The majority of oligofibrotic nodules are secondary to the disease and do not have an abnormal effect on lung function, so no treatment is necessary.
