Preoperative scintigraphic visualization of lymph nodes and pulmonary metastases from papillary thyroid carcinoma.
Preoperative accumulation of Tc-99m pertechnetate and radioiodine in metastases of well-differentiated thyroid carcinoma is uncommon. We report herein the case of a 39-year-old woman with occult papillary thyroid cancer revealed by widespread miliary lung metastases. Ultrasonography revealed the presence of an infracentimetric hypoechoic nodule and cervical lymph nodes. Scintigraphy, realized with Tc-99m pertechnetate and I-131 prior to thyroidectomy, failed to delineate the primary thyroid tumor, but revealed functional cervical nodes on the central and left lateral compartments, with pulmonary accumulation.
