Images in a 41-year-old man who underwent routine check-up. A 20 mm left thyroid nodule with isoechogenicity, mixed, smooth margin, wider-than-tall, and no calcification was found at grayscale US and assessed as a benign nodule. A score of 2 was assigned at elastography. The TI-RADS category was assigned as 3. This thyroid nodule was diagnosed as nodular goiter at surgery.
