Detection of metastatic thyroid carcinoma by 99mTc-pertechnetate in the presence of hyperfunctioning thyroid tissue.
Neck metastases secondary to thyroid cancer are rarely visualized scintigraphically in the presence of a functioning thyroid gland. We present a patient with cervical lymph node metastases that take up 99mTc pertechnetate in the presence of hyperfunctioning thyroid tissue and discuss the pathophysiology of this phenomenon.
