Lung lobular nodule is a kind of lung nodule, the severity should be determined according to the benign or malignant nature of the nodule, benign nodule is not serious, malignant nodule is more serious. Lung nodules are mostly benign, patients usually have no special discomfort, mostly found through physical examination, can not do special treatment, but should be regularly observed and followed up. If there is fever, cough, sputum, shortness of breath and other symptoms, may consider pneumonia, tuberculosis, etc., need to further improve the relevant examinations and tests, after a clear diagnosis, symptomatic and causative treatment, after regular treatment, the prognosis is generally very good. If the imaging manifestations of lung nodules are lobar sign, burr sign, pleural pulling sign, and the diameter is more than 8mm, or the nodules are found to be growing rapidly and changing in character during regular review, we need to be highly alert to the possibility of malignancy, which will be more serious, and we need to perform surgical resection as soon as possible to clarify the benignity or malignancy of the pathology, and to decide on the follow-up treatment. It is recommended that patients with nodules in the lower lobe of the lungs should consult a regular hospital in time and undergo regular review for early detection, early diagnosis and early treatment.
