Few foci of fibrosis in the apices of both lungs mostly suggest the possibility that the patient had a pulmonary infection. The first consideration is tuberculosis infection. Tuberculosis is prone to changes such as exudation, proliferation, nodules, fibrosis, and pleural thickening during the process of absorption treatment. If it is manifested as fibrous foci in both lungs, it mostly suggests incomplete absorption, but this condition is not infectious and does not require special treatment. Focal fibrosis at the tips of both lungs is also common in patients with chronic smoking and long-term exposure to dust, including masons, coal miners, chefs, hairdressers, tailors and other professionals. The formation of focal fibrosis at the tips of the lungs from long-term dust inhalation generally suggests chronic bronchial infection, and patients can have clinical manifestations or no symptoms, and only need dynamic observation through high-resolution CT of the chest. In conclusion, a few foci of fibrosis at the lung apices generally have no special clinical significance and do not require special treatment, and dynamic follow-up of high-resolution CT of the chest is sufficient.
