Bil hilar prominence with left upper zone calcified nodular lesion morphologically

I have two very old calcified spots on the left upper lung. Radiologist says I must have to show the treatment of tb for getting aus visa, however a very experienced chest specialist says these calcified spots could be for another past childhood reason and there is no need for showing treatment, the visa authorities only ensures by taking further tests that a person should not have active tb. Please state what should be the best strategy?

Calcified spots are a benign finding and probably scars, which are the residual of any one of a variety of lung infections anytime in your past life.  Calcified spots are not a sign of active tuberculosis (TB).  If you must investigate this to satisfy the authorities, you should have a tuberculin skin test (PPD) and if it is definitely positive should receive 6 months of prophylactic therapy.  If it is truly negative there is no medical reason to do further testing; you are not a threat to others and not at risk for developing active TB.  If the authorities insist on further proof, the next step would be to collect no less than 3 sputum samples for microscopic exam and cultures for TB.  If you are not coughing up any sputum, it can be induced, with relatively little discomfort, by the inhalation of a hypertonic saline solution.

Medically, these calcified lesions are of no consequence.  Bureaucratically, it is another matter.
