Determination of whether a pleural nodule is benign or malignant relies primarily on a pathologic puncture biopsy, but can also be aided by imaging methods such as CT.
Pathologic puncture biopsy is the gold standard for identifying the nature of the nodule. Guided by ultrasound or CT, the puncture tool is used to take several pieces of tissue from the pleural nodule, and then a series of treatments such as staining is performed for microscopic observation, which can clarify the nature of the nodule very well, but the operation is risky, and it needs to be carried out by a professional doctor, and pneumothorax may occur after the operation.
Chest CT can also assist in the diagnosis, through the examination, you can see the location and size of the nodule and whether the surrounding smooth, so as to determine the nature of the nodule.
The appearance of pleural nodules must seek medical attention.
