Calcified foci in the lungs do not usually cause pulmonary embolism, while pulmonary embolism can sometimes cause calcified foci to form in the lungs.
Generally, calcified foci are benign intrapulmonary lesions caused by inflammatory diseases in the lungs, such as those caused by tuberculosis, and in a few cases, they may form after recovery from pulmonary embolism, etc. These foci are similar to a kind of old scar tissue, and generally do not have a negative effect on the body.
In general, calcified lung foci do not require special treatment, but for some patients with large calcified foci in the lungs that cause symptoms, it may be necessary to treat the primary disease that formed the foci, for example, calcified foci formed by tuberculosis, anti-tuberculosis treatment is needed to prevent further expansion of the calcified foci formed by tuberculosis.
