Repeat CT three months after surgery for fine bronchial adenoma. Bronchial adenomas are benign tumors with malignant tendency and are divided into three subtypes: bronchial carcinoid tumor, cylindrical tumor and mucoepithelioid tumor, which are mostly asymptomatic. Surgical resection is the radical treatment for bronchial adenoma, and radiotherapy and chemotherapy are needed after surgery, but it may recur after surgery, therefore, review CT after surgery, and do the same type of CT, if it is scanning CT before surgery, do the scanning CT, and if it is enhancement CT, do the enhancement CT, which will have the significance of comparison, and it is better to do the examination in the same hospital. If the fine bronchial adenoma is reviewed three months after surgery, it is recommended to go to the hospital in time for a follow-up review under the supervision of the doctor.
