Hi,
my solid nodules turned out to be 100% benign and called adenomas which are overgrowth of thyroid tissue. Mine FNA'd atypical so out came 1/2 my thyroid in '07

Doesn't look serious, since there is no abnormalities on the doppler, but still worth an FNA. Get the biopsy and then you will have more information.
Thyroid nodules are present in almost 50% of the population. I would wait and see what the results are from the FNA.
