The term, "old infectious granulomatous disease" refers to the calcifications.  This is usually a result of tuberculosis (TB) or a fungal infection.  At some time in the past you inhaled germs into your lungs.  Since your purified protein derivative (PPD) skin test is positive it was most likely TB.  Your immune system was able to contain the infection so that it did not spread.  Whatever caused it is now inactive and not an immediate threat.  If, at some time you should have a prolonged illness and/or should your immune system becomes weakened, it would be good to keep in mind that whatever caused the calcifications could reactivate.  The good news is that this is very unlikely to happen.  For all practical purposes, the findings of this chest x-ray are of no consequence to your health.
