Lobar calcification foci are scar foci left in the lungs after the inflammation of the lungs has healed. They are commonly seen in the lungs after the healing of tuberculosis infection, and can also be seen in the lungs after the healing of general inflammatory infections that leave calcification foci. In this case, no special treatment is needed, as long as annual checkups and chest films or chest CT are done. If you find burrs or lobes around the calcified foci or shadows around the calcified foci continue to grow, you should be alert to the possibility of tuberculosis recurrence or scar carcinoma, and further examination, such as lung aspiration or bronchoscopy, should be performed to further clarify the pathological nature of the foci.
