Inflammatory nodules in the lungs are often caused by infections, are mostly curable with timely and effective intervention, and are usually not serious. Lung nodules can be caused by a variety of reasons. Inflammatory lung nodules are often caused by chronic inflammation in the lungs, commonly due to Mycobacterium tuberculosis infection or fungal infection in the lungs, which can be seen as round or round-like high-density shadows on chest radiographs and chest CT. Inflammatory nodules in the lungs can shrink or even disappear through active and targeted anti-infection treatment. Inflammatory nodules in the lungs, if caused by tuberculosis, appear in the chest as tiny nodules distributed along the bronchial vascular bundles, which may fuse into balls. Therapeutically asymptomatic and normal lung function nodular disease requires no treatment. Nodular disease with significant intrapulmonary or extrapulmonary symptoms, especially involving the heart, nervous system, etc., need to be treated with systemic glucocorticosteroids, commonly used prednisone. In addition to this, lung nodules may be caused by hyperplastic lymph nodes, which do not require special treatment. If inflammatory lung nodules do not disappear after anti-infection, the dynamics of the lung nodules should be closely observed to prevent malignant changes. Lung nodules sometimes cannot be identified as benign or malignant by imaging, and the nature of the nodules can be clarified by bronchoscopy or lung puncture to obtain pathologic tissue. If you find lung nodules, it is recommended that you consult a doctor in a timely manner, complete the examination under the guidance of the doctor, identify the cause of the disease, and follow the doctor’s instructions for treatment.
