Pulmonary nodules with a few burrs can be seen in benign and malignant diseases. There are no data on the chance of benignity. The description of a nodule with a few burrs alone does not determine the likelihood of a benign condition. If the edges of the nodule are smooth and dense, then it is more likely to be benign. However, if the lung nodule is found to have short burrs, unclear margins, lobulation is seen, pleural pulling sensation, etc., these signs are more often seen in malignant diseases. However, none of the above is the basis for a definitive diagnosis, and pathologic puncture is the main procedure for a definitive diagnosis. If the diagnosis is difficult, CT-guided puncture should be considered, and if necessary, surgical resection of the nodule should be performed to clarify the diagnosis, and then the next treatment plan should be determined according to the diagnosis. Patients who find burr nodules in the lungs should consult the doctor in time, complete the relevant examinations, make a clear diagnosis, and then take the corresponding treatment plan.
