Single hot 1 CM nodule on thyroid scan with normal thyroid blood panels & uptake. Chances of malignancy?

Single hot 1 CM nodule on thyroid scan with normal thyroid blood panels & uptake.  Chances of malignancy?

Not likely: "hot" nodules are rarely cancer and most often represent benign follicular adenomas. These are also known as "autonomous" nodules because they make thyroid hormone but don't respond to the body's normal signals telling them when to stop making the hormone. The vast majority of thyroid cancer nodules are "cold" on a thyroid scan. ...Read more

Nodule (Definition)

Any growth or deposit in the body or on its surface may be casually termed a nodule until its character is determined by the familiarity of the physician with it or by the results of a biopsy if it is not so obvious. The term is casual ...Read more

My uptake scan revealed thyroid nodules. What can I do?

My uptake scan revealed thyroid nodules. What can I do?

Hot nodules?: Hi. We need more information. I assume you're hyperthyroid and that's why the uptakes and scan were done. Scans can reveal "hot nodules" in an otherwise "cold" thyroid gland, indicative of autonomously hyper functioning nodule(s), or it can real "cold nodules" in an otherwise diffusely "hot" thyroid gland, indicative of a cold nodule in a Graves' gland. Were 6 and 24 hour uptakes normal or high? ...Read more

Hot or cold: Thyroid nuclear scan usually with iodine 123 will show whether nodule is active (hot, increased uptake, or nonactive (cold, decreased uptake).More cold nodules are cancer.For patients presenting with thyroid nodules greater than 1 cm. In diameter (up to 20% will be malignant). They should be carefully evaluated, and managed. If greater than 1 cm. Should be closely followed or biopsied. ...Read more

Why do the nodules of a multinodular goiter not show up on a i-123 thyroid uptake scan?

Why do the nodules of a multinodular goiter not show up on a i-123 thyroid uptake scan?

Scan shows activity: A thyroid scan looks for functioning thyroid tissue. Much of a multinodular goiter can be nonfunctional and thus not show up well or will blend into the background thyroid tissue. ...Read more

TSH is constantly suppressed.FT3 borderline high. FT4 borderline low. Tested 5 times. Thyroid uptake scan = *low 5.3% wo nodules. Please help explain.

Thyroiditis: Why are you having your thyroid tested? what are your symptoms? start from the begining. Medicine is not about scans and numbers. TSH is suppressed by the elevated T3 (liothyronine) as feedback inhibition. I would expect normal to high uptake but it can be low in some cases of Hashimoto's thyroiditis. thyroid scan in Hashimoto's thyroiditis can mimic a wide range of thyroid disorders. Thyroid may be burning out. ...Read more

My thyroid uptake scan showed a cold nodule but TSH is normal. Will it need to be removed? It's taking long to see an endo and lab rec''s fna.

My thyroid uptake scan showed a cold nodule but TSH is normal.  Will it need to be removed?  It's taking long to see an endo and lab rec''s fna.

Depends: Next step would usually be a thyroid ultrasound and fna. If the, "nodule" is a simple cyst (colloid cyst) then it will likely be aspirated, if a solid nodule it would be biopsied. Most of the time a solid nodule will be negative for malignancy. If positive for malignancy, surgical removal would be the norm. ...Read more
