Thanks for your question on Health Care Magic. I can understand your situation and problem. Any lung insult whether tuberculosis or pneumonia or Pulmonary contusions heal by following mechanism. 1. Fibrosis 2. Calcification 3. Bronchiectesis 4. Rarely complete resolution. First two are very common and leave permanent scar on lung which is seen on chest x ray life long. This is inactive, healed scar tissue. So no treatment is required. For your visa purpose, we need to prove that these scars are inactive, non infectious. For this you need to consult pulmonologist and get done CT thorax and bronchoscopy with BAL (bronchoalveolar lavage) analysis. If both are negative for active tuberculosis, than you can argue with visa authority about not having active, infectious disease and the scars seen on x ray are old, healed, inactive. Hope I have solved your query. Wish you good health. Thanks.
