The presence of multiple ground glass nodules in both lungs is a pathological manifestation of imaging, and the clinical treatment depends mainly on the etiology. The more common is tuberculosis caused by infection with Mycobacterium tuberculosis, which should be treated with early and standardized combination of anti-tuberculosis drugs, such as isoniazid, rifampin, ethambutol, pyrazinamide, streptomycin, butamycin and levofloxacin, etc. Generally, standardized treatment is completely curable. In addition, there are also non-infectious diseases, mostly seen in both lungs with idiopathic pulmonary diffuse interstitial fibrosis, which can be treated with glucocorticoids such as dexamethasone, methylprednisolone, prednisone, etc. If necessary, immunosuppressive drugs such as cyclophosphamide and the Chinese herbal medicine Leigengtang can be used in combination.
