Hello and hope you are doing well.
The opacities can be caused by chronic infections like tuberculosis, sarcoidosis and due to occupational lung diseases like silicosis, asbestosis etc. Tuberculosis can produce typical changes in X rays and typically affects the upper lobes. This further correlated with blood tests, which show a raised ESR and lymphocytes. Please discuss this with your doctor am sure he will provide further assistance.
Hope this helped and do keep us posted.
