F. Dede et al., Metastatic thyroid cancer occurring as an unknown primary lesion - The role of F-18FDG positron emission tomography, CLIN NUCL M, 26(5), 2001, pp. 396-399
Thyroid cancer can appear as metastatic disease of an unknown primary origi
n, and fluorine-18 fluorodeoxyglucose (F-18 FDG) positron emission tomograp
hic (PET) studies are helpful in the workup evaluation of these patients, T
he authors describe two patients who had metastatic disease from an unknown
primary lesion, F-18 FDG PET studies played an important role in localizin
g the primary malignant site in the thyroid gland, The utility of F-18 FDG
imaging in decreasing the number of procedures, cost, and inconvenience to
patients is shown clearly in both cases.
