[|AI|]  Thanks for your question on Chat Doctor. You are having old tb scar in right upper lobe most probably. If you had tb and took the treatment, healing has to occur. And in lungs healing occur by 1. Fibrosis2. Calcification3. Bronchiectasis4. Rarely complete resolution. Fibrosis and calcification are seen more commonly.  And on chest x-ray it gives appearance of fibrotic scar tissue. So one can not comment on these x-ray lesions whether they are active or inactive. So report has been mentioned like undetermined activity. You need sputum examination and bronchoscopy with BAD (BronchoAlveolar Lavage) analysis for TB for confirmation about your lesion whether it is active or inactive.  If both are negative than it is clear that your c ray lesions are inactive fibrotic scar.
