Hashimoto, multiple small hypoechoic nodules in ultrasound

[Caterinas1985]

Hello,

I'm pretty anxious about my US results.

- 11 months ago
I had an US with the following results: thyroid gland normal in size. 6 small hypoechoic nodules, 3 in right lobe and 3 in left lobe, the biggest was 3.6x3.4x1.9 mm. No abnormal vascularity and no evidence of any cervical lymphnodes seen.

- I repeated  the ultrasound a week ago and my thyroid got bigger (right lobe 51x17x15 mm, left lobe 51.8x15.7x15.2 mm, isthmus 4 mm)
Both lobes show hypoechoic nodules (10 overall - 4 in right lobe and 6 in left lobe). The biggest nodule now is 6,5x3,9 mm.

I am positive for both antibodies (thyreoglobulin and thyroid peroxidase), which is indicative of Hashimoto

I'm really concerned because all these nodules are hypoechoic. Can it be indicative of cancer? I have a history of thyroid cancer in my family. Is this US result usual for Hashimoto's thyreoiditis? Are these hypoechoic nodules indicative of inflamation?

I'm awating repeated TSH. Last year my TSH was 1,7 and T3/T4 within normal range.

Thank you!
