Possible False Positive PET scan?

Hi all, I was diagnosed with Stage 4 NHL (Follicular/DLBCL) in October and have had six cycles of R-CHOP and one of Rituximab. 

After cycle 7, my oncologist booked a PET scan that showed some new spots in the liver. He started talking about refractory lymphoma and said we needed a biopsy to see which of the two it was and that I would need to go on a trial or have a SCT or some other treatment. 

I had an ultrasound to see if they could get an ultrasound guided biopsy done. That showed one spot instead of the three that showed up on the PET scan. And the one spot was in a difficult to access area. 

They decided that the other spots may be in the stomach, not the liver, so I had a gastroscopy a week ago to see if they could do a biopsy. They found nothing more than some kidney inflammation, scar tissue and a gallstone -- certainly nothing to biopsy. 

Now I have to have the liver biopsy, probably in the next week.

Has anyone had things pop up on PET scans at the end of treatment, or close to the end of treatment, that turned out not to be cancer? I'm hoping that the biopsy just shows inflammation, but I'm not sure what conditions show up on a PET scan. I can't find anything that definitively tells you what sort of liver conditions can light up.

So could I ask you to copy and paste this into the group as this will open up your concerns to a wider group of people who know exactly what you are going through at the moment...... and I will give you my thoughts in this new post and keep everything together.
