Papillary Thyroid Carcinoma
Papillary thyroid carcinomas (PTCs) are solid, usually hypoechoic tumors with inhomogeneous echo structure. They usually have irregular margins and often contain discrete echogenic foci, ie, microcalcifications. They may be solitary or multifocal. In our experience the vascularity varies from avascular to strongly vascularized. In our opinion, the ultrasound findings with highest accuracy for PTC show low echogenicity, microcalcifications, irregular margins, and neck lymph node metastases [4,6–10]. Uncommon features include hyperechoic or mixed echo texture, cysts, hypovascularity, and coarse or peripheral calcifications .
