Thanks for your question on Health Care Magic.
I can understand your friend's situation and problem.
Current
x ray findings and previous findings are almost same.
This suggest that your friend is having old, healed, inactive scar tissue.
To solve visa problem, I advise her to
consult pulmonologist and get done
1. CT thorax with Contrast.
2. Bronchoscopic evaluation and BAL (
bronchoalveolar lavage) analysis.
CT thorax is superior than chest x ray in diagnosis of old scar lesions.
Bronchoscopy and BAL are also more diagnostic in diagnosis of active infection.
If both of these are negative for
active tuberculosis than, she can argue with visa authority about not having active, infectious disease and the lesions seen on chest x ray are old, healed, inactive, fibrotic lesions.
So ask her to consult pulmonologist and discuss all these.
Hope I have solved your query.
Wishing good health to your friend. Thanks.
