Lymph node calcification in the right hilar is most often caused by chronic infectious diseases of the lungs, and tuberculosis is more likely to be considered. Tuberculosis infects the body with plaques, exudates, proliferation, nodules, calcification, and cavity formation, and is prone to develop an immune response in the lungs, especially the hilum, resulting in lymph node calcification. Long-term smokers and people who are exposed to dust, including stonemasons and coal miners, are also prone to lymph node calcification at the hilum due to long-term inhalation of silica dust. Lymph node calcification at the hilum is mostly benign and is caused by chronic infectious diseases of the lungs, including bronchiectasis, lung abscess, pulmonary fibrosis, and other infectious diseases, which are prone to form lymph node calcification at the hilum. Lymph node calcification does not require special treatment, and CT can tell how much calcification is present and whether it has progressed. For this reason, a chest CT is needed once a year to keep a dynamic eye on the changes in calcifications.
