Abstract:
A 44-year-old euthyroid woman had two palpable nodules in the thyroid gland. 123I thyroid scintigraphy showed a hot nodule in the right lobe and a cold one in the left lobe. Total thyroidectomy was performed, and histopathologic examination revealed that both tumors contained papillary carcinoma. Thus, hot nodules on a thyroid scintigram with 123I do not necessarily preclude malignancy.
