The presence of 8 mm foci of glassy nodules with blurred margins may be considered as a result of infected foci or localized hemorrhage in the lung tissue, as well as malignant tumors of the lungs. 1. Infected foci: when the lung tissue is infected with fungi or viruses, it will lead to the appearance of glassy nodules with blurred edges, which need to be effectively treated by taking antibacterial or antiviral drugs. Bacteriostatic drugs can choose amoxicillin, levofloxacin and so on, while antiviral drugs can choose oseltamivir, amantadine and so on. 2. Hemorrhage: when the lung tissue has localized damage and caused a small amount of bleeding, it may also lead to localized glassy nodules and blurred edges on the image, which can be effectively treated by taking hemostatic drugs, such as thrombin, vitamin K and so on. 3. Malignant tumors: for the smaller size and fuzzy edge of the grinding glass nodule also need to consider the possibility of lung malignant tumors, it is recommended to go to the hospital in time for pathological section or histological examination, if the diagnosis of malignant tumors, should be carried out as soon as possible for surgical resection. In the case of ground-glass nodules with blurred edges in the lung tissue, the specific cause of the disease should be determined, and appropriate medication should be chosen under the guidance of the doctor or surgical treatment should be carried out at the earliest possible time.
