So little known

I have recently been diagnosed with mycobacterium interjectum.
It started with multiple lung nodules and I was given a bronchoscopy.  8 weeks later the results came back as M. interjectum.  My infectious disease knows very little about it.
I had a thoracoscopy last week but the final biopsy has not been received.  The surgeon says nodules are granulomas not cancer.  I guess my question is?  Do you know anything about this rare infection?  Does it cause lung nodules?  I am asymtomatic.  No lung problems.  Should I be worried?

Mycobacterium interjectum is a rare nontuberculous mycobacterium that is found in the environment.  You were most likely exposed to air borne M. interjectum and inhaled the germ into your lungs.  This can cause disease.  It would be reasonable to simply watch for symptoms and chest x-ray changes.  The germ could be sent to the mycobacterial lab at National Jewish Medical and Research Center for susceptibility testing.  Then it would be known what treatment would be most effective against the germ.  So if there is progression, treatment could be selected on a rational basis.  Please read our NTM information at http://www.nationaljewish.org/disease-info/diseases/nts-mycobac/index.aspx to learn more.
