[|Human|] hi, I m 34 years old, 5 3 , 54 kgs. I don t have any history of PTB or other lung diseases but my recent x-ray result shows that I have a fibrosis on my upper right lung. what causes it? is there any way to cure it or dissolve the scar tissue? pls help me.. I was not cleared with my medical exam for employment because of this..hoping for your answer. thank you
[|AI|]  Thanks for your question on Chat Doctor. Any lung insult whether TB or pneumonia or trauma can cause scar. In lung, healing can occur by 1. Fibrosis2. Calcification3. Rarely complete resolution. So having a scar on chest x-ray does not always mean you had TB in the past. It can be seen with trauma or pneumonia too.Similarly, scar does not tell you anything about activity of the disease. So in my opinion you should first consult pulmonologist and get done CT THORAX and Bronchoscopy and BAD (Bronchi Alveolar Lavage) analysis for TB. As CT gives much better idea than chest x-ray about lung parenchymal. If both are negative than you can argue visa authorities about not having active TB.
