    Question does the isthmus shrink on its own?/confusing sono results

    Hi everyone
    recently had a thyroid sono to check on 3 right side nodules. details are below, bu my question is

    my new endo (we moved and the old one was just too far away) reviewed the reports and told me nothing had changed and that i should wait a year or two for another sono.
    some things grew, while others shrank (the isthmus by half, (guess thats a good thing)but i am abit concerned about the 2nd nodule which seems to be growing, and the new left side nodules. should i just wait it out or ask my endo to revisit the results?

    Back in 2008 my first sono the dimensions were:

    right side 5.6x2.1x22cm
    1st nodule was an isoechoic nodule with calcification measured 1.8 x 1.0x.6cm
    2nd nodule was a hyperechoic nodule without calcification measuring 1.2x1.1x1.1cm

    left side was 4.2x1.9x1.6 with no significant masses

    isthmus measured 5mm

    2010 sono showed:
    right side 5.8x2.4x2.3cm
    1st nodule was now listed as hypoechoic with calcification measuring 1.8x1.1x.7cm
    2nd nodule now listed as isoechoic without calcification measuring
    and a new third nodule measuring 1.0x1.x0 cm

    left side measures 4.5x 1.7x1.8 cm - no masses found

    isthmus measured 8mm

    2012 sono showed
    right side 5.5x2.2x2.4cm
    1st nodule now listed as a complex nodule with calcification measuring 1.8 x 1.2 x .9cm (just grew a tiny bit)
    2nd nodule listed as a solid isoechoic measures 1.9 x 1.7 x 1.4cm
    third nodule measures .7 x.7 cm

    left side measures 4 x 1.6 x 1.6cm
    1 solid complex nodule measuring .7 x .7 cm
    2nd nodule densely calcified measuring 2mm

    isthmus now measures 4mm

    My endo would just do an fna/biopsy on the larger ones in his office-have you ever had one? Don't know why your endo. has an aversion to a quick fna to check these things out and ease your mind. They are likely nothing. You can always go back and check in 8 months to a year, and ask for an fna. Sounds like everything is somewhat stable. No rush to worry.
