[|Human|] I was recently diagnosed with ovarian cancer, stage IIC.  A PET scan last week indicated "several small hypoattenuating nodules in the right lobe of the thyroid gland, non-FDG avid."  "Calcified small mediastinal nodes" were noted in the chest, as well as "a 4 mm right middle lobe nodule and a 3 mm left lower lung lobe nodule." Also noted on this scan was a "1.1 cm non-hypermetabolic hypoattentuating lesion in the left lobe of the liver, not FDG avid."What does it all mean?  (I did start chemo for the ovarian cancer today.)Thank you,Jane
[|AI|]  Hi and welcome to Chat Doctor, thank you for your query. Well, Pet ct scan is very sensitive but not specific, and it has significant rate of false positive results. If you ask me are these nodules malignant metastases of ovarian cancer then I am not so sure and would say that it is not likely to be metastases since ovarian cancer has a bit different spreading potential and pet scan features would be different too. But it requires further follow up and frequent diagnostic tests to verify do these nodules grow or not. Wish you good health. Regards.
