me neither - that term is something I can't relate to. But in the report the gland sounds like you have some inflammation to me there and that too can be causing some pressure with your complaints listed.
What autoimmune thyroid labs have you had done with blood?
6 mm is too small to biopsy, they can't tell if it is hot/cold on an ultrasound, they need to do a nuclear scan. Until it gets to 1 cm, you can only watch it and when it gets big enough, they can biopsy it. Tiny nodules probably are not the cause of your hoarseness, although they can be in rare cases. There is a nerve running through the thyroid that controls vocal function, it may be affected by nodules, but yours are small. You might have an ENT check your vocal chords, and also check you for GERD. As for the sclerosis, I have never heard that term, probably has to do with the texture.
