title: Radiotracer uptake in medullary carcinoma of the thyroid.
abstract: A patient with pathologically confirmed medullary carcinoma of the thyroid with lymph node metastases was noted to show uptake of radiothallium, radiopertechnetate, and radioiodine. A perchlorate washout test was markedly positive, indicating that the uptake was largely due to trapping.
