A US findings before FNA. An iso-hypoechoic mass (22.6 mm × 12.8 mm × 9.6 mm) is shown in the right lobe of thyroid gland. B US findings 5 min after FNA. The thyroid gland is massively enlarged; hypoechoic areas demonstrate a crack-like pattern, and there is fluid retention a few millimeters thick in the subcapsular area of the thyroid gland.
