Echogenicity of thyroid cancer (arrow). (A) Isoechoic nodule on the posterior aspect of the right thyroid gland. The nodule has similar echogenicity to the thyroid gland. (B) Hypoechoic nodule on the medial aspect of the left thyroid gland. The nodule has hypoechoic echogenicity compared to the thyroid gland. (C) Markedly hypoechoic nodule of the left thyroid gland. The nodule has more hypoechoic echogenicity than that of strap muscle.
