The majority of pulmonary cornu nodules do not heal spontaneously, which is only a pathological feature of the morphology detected by imaging. The most common clinical features are as follows: firstly, nodular shadows around the terminal and respiratory fine bronchi of the lung are mainly common in pneumoconiosis, or allergic alveolitis, which require glucocorticoid therapy. Secondly, lymphatic inflammation due to cancerous lymphatic metastasis, which requires surgery, supplemented by radiotherapy and chemotherapy, in order to heal. In addition, pulmonary tuberculosis with hematogenous dissemination requires a combination of standardized anti-tuberculosis drugs to achieve a cure. Most pulmonary nodules require medical intervention to achieve a cure.
