how many thyroid nodules are benign? |
about 95% |
|
|
and what % of men and women can present with a thyroid nodule? |
5% of women
1 % of men |
|
|
What is the most common cause/type of a thyroid nodle? |
benign collection of colloid material |
|
|
how often do nodules associate with hyper/hypo symptoms and presentation? |
it's very rare to present this way |
|
|
So a woman presents with a thyroid nodule, and is completely asymptomatic. The nodule is non-tender. What is the next step in mgmt.? |
you get a TSH and T4 then follow from afar essentially |
|
|
Why do you get a TSH and T4 here>? |
because it tells you whether it's a hot or cold nodule |
|
|
What does a hot nodule mean? |
it means that it's NOT malignant. rules out cancer functionally. |
|
|
And what does a cold nodule mean? |
it means the possibility of malignancy still exists |
|
|
When do you have to do FNA on a nodule? |
when it's over 1 cm |
|
|
What comes BEFORE FNA? |
you've ruled out a hot nodule with TSH/T4
and you've done an ULTRASOUND to confirm its size is sufficiently large to indicate a biopsy |
|
|
But if you can feel that the nodule is over 1 cm in size... |
then U/S is NOt indicated. it cannot be used to evaluate likelihood of malignancy so it doesn't really tell you very much |
|
|
So basic workup is: |
Perform TSH and T4
If tests are normal--> biopsy |
|
|
If the nodule is biopsied and path shows "indeterminant for follicular adenoma" what do you do? |
it needs to be excised, surgical/excisional biopsy
|
|
|
Why removal? |
because the result of follicular adenoma actually CANNOT rule out cancer. the only way to exclude a malignancy is to completely remove the nodule |
