As curableness and survival rate are increased with modern cancer treatment approaches, the frequency of second primer tumor disease has also increased especially elderly patient. Although coexistence of other primary malignancies is relatively higher, thyroid carcinoma is not one of the most common cancers in patients with renal cancer. We reported that thyroid carcinoma was detected as a result of the evaluation of incidental thyroid nodule which was false negative fine needle aspiration and positive involment in [F-18]-2-fluoro-2-deoxy-D-glucose-positron emission tomography/Computed tomography in patients who were diagnosed with renal cell carcinoma for three years. In conclusion; it should be kept in mind that fine needle aspiration biopsy can be false negative for the evaluation of thyroid nodule. The focal involment in thyroid [F-18]-2-fluoro-2-deoxy-D-glucose-positron emission tomography/Computed tomography a high risk of malignancy, especially in cases with high maximum standardized uptake values.
