1. Pulmonary fibroadenoma: refers to the fibrous scar tissue formed by the self repair mechanism of lung tissue after being stimulated by inflammation, infection, injury, etc. It is the repair manifestation of lung injury. It is often caused by physical and chemical factors (such as long-term exposure to dust, harmful gases, etc.), infectious factors (such as the lungs having been infected by pathogens such as bacteria, viruses, fungi, etc.), and autoimmune diseases (such as rheumatoid arthritis, systemic lupus erythematosus, etc. affecting the lungs).
2. Pulmonary calcifications: mostly refer to calcium deposits with strong echoes or high-density imaging in the lungs, usually visible on CT. Most of them are caused by inflammation, tuberculosis infection, and lung fluke infection. It is a manifestation of lung inflammation after healing, which may be scars left after treatment from previous pneumonia, or calcification that gradually appears during anti tuberculosis treatment for tuberculosis.
3. The difference between the two: Pulmonary fibrotic lesions may lead to decreased respiratory function, which needs to be diagnosed through examination and treated according to the situation; The calcification focus is mostly seen in old pneumonia, tuberculosis and other diseases, which generally has little impact on respiratory function, and usually does not need special treatment, just pay attention to healthy life in daily life.
