I am an American living in Thailand. In 2004 I had a pulmonary embolism. I recently had a chest X-ray which showed a calcified granuloma in the right lung near where one finds the vena cava. Immigration thinks it may be TB. I have taken three consecutive early morning sputum acid fast tests and a PPD, all of which are negative. Is this enough information to satisfy the question of TB vs a granuloma secondary to the pulmonary embolus?

Thank you for your timely reply.


It appears that you are undergoing a diagnostic evaluation designed to answer the question of whether or not you have active pulmonary tuberculosis at present. Without knowing the details of the immigration requirements pertinent to your case or care, it is not possible to answer your question.
