Abstrakt: Sonography, computed tomography and magnetic resonance imaging examinations did not detect recurrence or metastases of medullary thyroid carcinoma (MTC) in a patient with a rapidly rising serum calcitonin concentration after total thyroidectomy. Scintigraphy with technetium-99m labelled anti-carcinoembryonic antigen antibody, Tc-colloid and iodine-131 metaiodobenzylguanidine indicated liver metastases. The three scintigrams were to some extent discrepant but from the combined information the diagnosis of hepatic metastases could be established; it was subsequently verified by sonography and aspiration biopsy. This case demonstrates the usefulness of applying nuclear medicine imaging methods for the localization of hepatic MTC metastases. [ABSTRACT FROM AUTHOR]
