How accurate is the puncture examination?

The doctor replied: Neither hospital is wrong, and both the results are correct for the following reasons: For a mass or nodule in the lung, during percutaneous lung puncture, if the tissue taken out is located at the edge of the mass or nodule, it is very difficult. It may be inflammatory tissue, and the conclusion of inflammatory pseudotumor is drawn; if the central caseous necrotic tissue is taken out, tuberculosis may be considered, so the conclusion drawn by percutaneous lung puncture completely depends on the location of the taken tissue. Since the lesion itself may be relatively small, if the site is relatively deep, or there are many factors such as poor patient cooperation, it cannot be guaranteed that every puncture will be perfect. In addition, the specimens taken out by surgery are also taken from multiple points of the specimens during the pathological examination, and the conclusions drawn are naturally the most accurate. In conclusion, there is definitely an error between percutaneous lung biopsy and surgical pathology, and sometimes it is very large, which is unavoidable.
