Why do fibrous lesions appear in the right middle lobe of the lung?

Many friends do not feel lung problems such as coughing and chest tightness in normal times, but they will find fibrous foci in the right middle lobe of the lung during physical examinations. They feel very puzzled about this and do not know whether they have any lung disease. In fact, fibrous foci in the right middle lobe of the lung are relatively common in our lives. You can read the analysis in this article to find out why fibrous foci in the right middle lobe of the lung appear.

Pulmonary fibrosis is often the fibrotic lesion left over after natural healing of lung infection. The interstitial tissue of the lung is composed of collagen, elastin and protein sugars. When fibroblasts are damaged chemically or physically, they will secrete collagen to repair the interstitial tissue of the lung, thereby causing pulmonary fibrosis; that is, the result of the body's repair after the lungs are damaged. Fibrous lesions are a manifestation of old sexually transmitted diseases. If the right lung has been infected (whether you have tuberculosis or other lung diseases), the active lesions during the infection will heal after treatment, and there will be fibrotic changes in the lesioned areas of the lungs.

The fibrous lesions are not a serious problem and do not affect lung function. Local fibrosis is commonly caused by old tuberculosis infection foci (in fact, many people are infected with tuberculosis without knowing it and recover on their own). Pulmonary fibrosis itself is also a disease, which is related to immune damage. It is the immune system that attacks its own lung tissue and causes fibrosis. Judging from your situation, it is not pulmonary fibrosis, and there is no big problem from the imaging examination.

Suggestions: The etiology of the formation of pulmonary fibrosis is mainly as follows: early onset of alveolitis, the presence of serous and cellular components in the alveoli, a large number of monocytes, some lymphocytes, plasma cells, alveolar macrophages and other inflammatory cell infiltration in the pulmonary interstitium, and intact alveolar structure. In the late stage, chronic inflammation has been alleviated, the alveolar structure is replaced by solid collagen, the alveolar wall is destroyed, and an expanded honeycomb lung is formed.

After understanding what the fibrous foci in the right middle lobe of the lung are, I believe you will no longer worry about this problem. However, in order to prevent our lung function from being affected and to make our bodies healthier, it is recommended that you change your lifestyle habits such as smoking that may affect lung function, so that you can better protect our lungs!
