I had full TT in 2019 due to graves thyrotoxicosis, as some members will know I had a US scan performed in 2022 for a Parathyroid adenoma, the surgeon noted a nodule of 6/7 on the left side, but nothing else.I went on to have the F18 pet scan to determine what the nodule was, but a mass of (14x7x21) up took on the right side, FNA showed it to be thyroid tissue.
I was first researching as to whether the mass could be producing thyroid hormones, I went on to a site where an Indian endocrinologist said "in cases of partial thyroidectomy the thyroid can regenerate, and if you had graves it could come back as graves, in that it could be auto immune again.
However if your had total TT the chances of your thyroid regenerating is extremely unlikely, in these cases it would be that the thyroidectomy had been performed incorrectly .
Mine as grown back on the right side, there were plenty of posted the same as mine saying after there TT thyroid tissue as grown back, one person in the US was told if you have full TT your symptoms of graves will go, and she found that to be the case... But for 15 years she as never took any thyroid medication 😲.. But her thyroid as grown back.
One post asked her if she was being honest, as if she had no thyroid, how was she feeling not taking any thyroid replacement? And if this were true she was very lucky, she said she felt OK, and was never told to take thyroid medication as the surgeon told her TT would cure her.. but recently she started to have hyper symptoms again and had a US scan which showed her thyroid had grown back 🤔
So she wondered if she'd been producing thyroid hormone again and that's why she felt ok🤷♀️
This is something I will be asking at my endocrinologist appointment 👍
The thyroid... Its a weird thing🤦♀️
