The symptoms of multiple patchy ground glass shadows in both lungs depend on the nature of the patchy ground glass shadow. If it is an infection that causes multiple patchy ground glass shadows, there is usually coughing, fever, coughing up sputum, and in some cases, even coughing up blood, difficulty breathing, and feeling unable to catch their breath after walking a short distance, which indicates an infection and acute inflammation, and can be cured by anti-infection treatment. There is also a case of multiple patches of ground glass shadows in both lungs that are not infections, but multiple pulmonary nodules, only manifested as ground glass shadows, which should be especially noted if the ground glass shadows are large and scattered in both lungs, from the upper lobe to the lower lobe, the following two conditions should be noted: 1. Or in the stage of atypical hyperplasia, carcinoma in situ or invasive carcinoma, when it is more tricky to deal with multiple ground glass nodules. Because there are so many nodules, the surgeon will lose lung function if he or she treats all of them, and it is not a good idea to leave so many nodules untreated. This is when the doctor will recommend an internal treatment, called ablation therapy. This method is less invasive, has no significant impact on lung function, and is effective in treating larger or more malignant ground glass nodules by radiofrequency ablation.
