Bingo!  I suspected she had high cholesterol.  

The woman who was diagnosed with lipid pneumonia had been taking Lovastatin to lower her cholesterol.  I suspected early on that the fat / lipid was coming from the body (not because of the liquid itself but somehow could be a reaction to the liquid).  In fact, that's exactly what my OP in this thread is about.  I don't know if the hygroscopic nature of the liquids can "draw fat" into the lungs.  That might be total nonsense.  

It does seem as if "heavy lung" itself is some form of pneumonia.  

This was a great find (thanks to Guillermo González for his comment).  http://tobaccoanalysis.blogspot.com/2013/06/german-cancer-research-center-corrects.html
