Thanks for your question on Healthcare Magic. I can understand your concern. Not only pulmonary tuberculosis, pneumonia or lung trauma etc can also produce scar lesions after healing. Since these scar lesions are inactive and non infectious, no treatment is required. For your visa purpose we need to prove that these scar lesions are old, healed lesions and not due to active infection. SFor this, you need to consult pulmonologist and get done clinical examination of respiratory system, CT thorax and bronchoscopy with BAL (bronchoalveolar lavage) analysis. If all these are negative for active infection, you can argue with visa authority about having old,healed, non infectious lesions. Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
