I had my medical last year because am planning to go abroad. I've been x-rayed for 3 times but my x-ray results are not consistent. The first finding is that nodular density at the left apex so i was then recommended for a tuberculin test and the result is negative. and then I was then recommended for another x-ray again and the result is granuloma. So, since the results of my x-ray is not consistent, I decided to have a second option with another diagnostic center I had xrayed there but the result of my x-ray again is semi-lodortic focus at the left apex. Could someone here help me about the explanation of my x-ray results?
