Frosted glass shadows in the lungs are abnormal lesions in the lungs, and the specific treatment plan is closely related to the type of disease, which mainly includes regular checkups, medication and surgery. 1. Regular checkups: small ground-glass nodules do not have any symptoms and do not require much intervention for the time being, so pay attention to the checkups in half a year to one year first. 2. Anti-infection treatment: all kinds of infections, including bacteria, mold, etc., can be caused by bacterial infections, antibiotics (cefaclor, ornidazole, etc.), mold infections can be applied to antifungal drugs (itraconazole, terbinafine, etc.); allergies and other causes can also cause ground-glass density shadows, can be applied to anti-allergy drugs (loratadine, etc.), as well as hormonal drugs (prednisolone, etc.). 3. Surgery: If the lesion is malignant or confirmed to be malignant by puncture, radical resection can be considered. The presence of ground-glass nodules in the lungs requires timely medical observation and standardized treatment under the guidance of clinicians.
