Lung nodules may develop after the removal of pulmonary hernias, related to the proliferation of fibrous tissue after the removal; or the lungs may develop other diseases that manifest as pulmonary nodules, including benign or malignant diseases. Lung bullae are caused by elevated air pressure within the alveoli rupturing and then fusing with each other, and the disease can be treated by surgical procedures such as resection or incision of the bullae, ligation or suturing of the bullae, and lobectomy to improve ventilation of the lung tissue. In some people, fibrous tissue proliferation forming fibrous striae or nodules occurs in the lung tissue after resection surgery, at which time malignant nodules should be excluded. Lung nodules may appear on lung imaging after pulmonary herpetic resection, when they may also be unrelated to the pulmonary herpetic and due to other diseases of the lungs. This includes benign diseases, such as lung infections, pulmonary hemangiomas, pulmonary malignant tumors and other benign tumors; and malignant diseases, such as primary malignant tumors of the lungs and pulmonary metastases. If lung nodules appear after pulmonary herpetic resection, it is recommended to consult the doctor promptly for pathologic biopsy to clarify the nature of the nodules, and then treat them according to the specific situation.
