Whether the patchy glassy hyperdense shadow in the lower lobe of the right lung is serious or not is mainly judged by the condition of the lesion itself, such as pneumonia or tuberculosis, which is generally not serious and can be recovered through treatment, while the tumor-like lesion is a serious condition, which is easy to affect the life if not controlled in time. 1. Pneumonia: If there are bacterial or viral infections, patchy glassy hyperdense shadow is mainly considered to be caused by inflammation and exudation, and most of them will be gradually absorbed by themselves after treatment with medication, which is not a serious condition. 2. Tuberculosis: caused by Mycobacterium tuberculosis infection, often with low-grade fever, night sweats, and patchy ground-glass high-density shadows in the lower lobe of the right lung, which will be gradually recovered after anti-tuberculosis treatment, and is generally not serious. 3. Tumor lesion: the corresponding lesion has a certain tumor pattern, and in the process of review, the lesion becomes real or continues to increase in size, and is further examined to be lung cancer, which is a relatively serious condition, and if it is not controlled in time, there may be invasion of the surrounding tissues and distant metastasis, which will seriously affect the state of life. The discovery of patchy ground-glass-like high-density shadow in the lower lobe of the right lung, accompanied by obvious chest pain and cough, requires timely medical treatment, firstly to determine the condition, and then to carry out standardized treatment under the guidance of clinicians.
