Shrinking thyroid glands - good or bad?
I have two ultrasound reports over the past several months which appear quite different from one another:
Right gland measures 4.73cm x 2.14 x 2.35. Left measures 5.1 x 2.01 x 1.67. Isthmus is .51 cm. Scan shows mildy diffused flow, mild prominent glands, and no discrete thyroid nodules. According to the report, it says the pattern would be consistent with either Hashimoto's or Graves (but doesn't exactly say why).
Right lobe measures 3.5 x 2.0 x .9. Right lobe has a .4 x .4 cm hypoechoic node.
Left lobe measures 3.5 x 1.8 x 1.1, with multiple hypoechoic nodes, .2-.4 cm. Hypoechoic nodes in both lobes, recommend to check with nuclear medicine thyroid scan.
For the thyroid experts out there... what does this mean exactly? Did inflammation go down, resulting in a smaller thyroid? Or... are antibodies destroying my thyroid, making it smaller? And now I have small nodules, where previously I didn't.
My blood work came back with normal hormone levels, but a TSH in the low 3s. Hashi antibodies tested positive during both ultrasounds, but my TGab was the only high one, around 220 for the 8/18 test. For the 11/14 test my TGab came down to 40 (test range 0-40).
Anybody have any ideas as to what's going on with my thyroid?
