Figure 3

Hypoechoic thyroid nodules with various degree of hypoechogenicity. (A) Markedly hypoechoic nodule (hypoechoic relative to the anterior neck muscles) Diagnosis: Conventional papillary thyroid carcinoma (B) Moderately hypoechoic nodule (similar echogenicity to the anterior neck muscle). Diagnosis: Conventional papillary thyroid carcinoma (C) Mildly hypoechoic nodule (hypoechoic relative to the normal thyroid parenchyma, but hyperechoic relative to the anterior neck muscle). Diagnosis: Follicular variant papillary thyroid carcinoma.
