Images in a 28-year-old woman who underwent routine check-up. A 16 mm left thyroid nodule with no echo, cystic, smooth margin, wider-than-tall, and no calcification was found by grayscale US and assessed as a benign nodule. A score of 0 was assigned at elastography. The TI-RADS category was assigned as 1. This thyroid nodule was diagnosed as a nodular goiter with cystic change at surgery.
