Rapid growth and signs of possible invasion, such as pain or hoarseness, are most suggestive, but not conclusive of malignancy
Clinical groups with the highest risk for malignancy in a thyroid nodule are children, males, adults younger than 30 or older than 60 years, and those exposed to radiation therapy, especially during childhood
Serum Tg has been reported as useful in predicting a well-differentiated carcinoma
Radioisotope Scanning
radionuclide scans allow assessment of thyroid function.
Technetium pertechnetate (99mTc) is taken up rapidly by the normal activity of follicular cells. It is trapped by follicular cells, but not organified. 99mTc has a short half-life and low radiation dose. Its rapid absorption allows quick evaluation of increased uptake (so-called hot) or hypofunctioning (so-called cold) areas of the thyroid.
123I and 131I iodine scintigraphy is also used to evaluate the functional status of the gland
Advantages of scanning with 123I include a low dose of radiation (30 mrad) and short half-life.
123I is a good choice for evaluating suspected lingual thyroids or substernal goiters.
131I has a longer half-life (8 days) and emits higher levels of β-radiation. 131I is optimal for imaging thyroid carcinoma.
screening modality of choice for the evaluation of distant metastasis.
