Abstract: The differential diagnosis of thyroid nodules in patients treated for renal cell carcinoma in the past can be
challenging unless they present sonographic features of malignancy. The possibility of metastases to the
thyroid gland, even many years after the primary occurrence of the renal tumor, should always be
considered. Here, we present the case of a patient diagnosed with metastases of a renal cell carcinoma to
the thyroid 22 years after nephrectomy of the left kidney and uneventful follow-up.
Keywords: Renal cell carcinoma, metastases to the thyroid
