You are going to have to talk to your doctor for sure but I think it means that the "mass" in your right lobe is not made up of thyroid tissue - meaning it shouldn't be there. It looks like your thyroid may be pretty much non-functioning too. Not an endo or a radiologist but that's my take on it.

The next step would probably be a PET scan.

Thanks for the advice .... I've tried to access the website you posted, but so far without any luck! I'll keep trying!
Would a FNA be something to consider 'next,' too???
I thought I'd add that my TSH is 0.8 and my antibodies are negative. Not sure what that means either!!!!
I am impressed at the knowledge on this board .... !! Thanks for sharing!
