Re: Anyone had ectopic or remnant thyroid after TT?
I had a strip of thyroid still in my neck after removal. They said when one is a fetus, the thyroid is actually the tongue before it becomes your thyroid, so it wasn't uncommon to find a strip of thyroid high up in my neck.
In my case this made a difference because I had thyroid cancer and I had to ablate all thyroid tissue to prevent a recurrence.
I think you can have thyroid tissue anywhere in your chest or neck, and I think it can produce hormone wherever the cells may be.
