Pulmonary hairy glass nodules, which can be seen in pneumonia, can also be seen in lung cancer. If the nodules are relatively small, it is recommended to review them after anti-inflammatory treatment, and if the nodules are relatively large, they can be directly punctured for pathology. Many people find hairy glass-like nodules in the lungs during physical examination, so don’t worry too much at this time. If the nodule is small, the most likely cause is inflammation, in this case directly use anti-inflammatory drugs, anti-inflammatory treatment for two weeks and then recheck, if the nodule shrinks or disappears, it is considered to be caused by inflammation. If the nodule is larger than one centimeter, it should be taken seriously. It is recommended to perform bronchoscopy or lung aspiration to obtain pathology and make a diagnosis according to the pathology, and if it is malignant, surgery should be actively taken. In addition to inflammation and tumors, other diseases such as tuberculosis, fungal pneumonia, silicosis, and pulmonary fibrosis can also be seen. These need to rely on the examination to identify, if only to do plain CT is difficult to identify, generally recommended to do enhanced CT, conducive to the identification of disease.
