Metastatic lymph nodes from papillary cancer detected using 99Tc pertechnetate

ABSTRACT

This is a case report of a 51-year-old female diagnosed with papillary microcarcinoma of the thyroid gland after undergoing total thyroidectomy. A 99mTc pertechnetate thyroid scan was done before radioiodine ablation therapy. It showed cervical neck lymph nodes taking up the radiotracer. Another scan after ablation therapy showed the same nodes taking up the therapeutic iodine131. The paper discusses using 99mTc pertechnetate to detect thyroid cancer metastases.
