Figure 3

(a) A 63-year-old male, who was found to have a very hypoechoic solid nodule of the thyroid, with ill-defined margin and posterior echo attenuation. It was classified as TI-RADS 4. (b) CEUS showed no enhancement at all in most areas of this nodule, and only the edge of the nodule showed regular annular enhancement with clear margin. (c) The aspirate of the FNAB was a dry brown substance. (d) Multinucleated giant cells and hemosiderin were easily to be seen in cell pathology (x200).
