Abstract

Medullary thyroid carcinoma (MTC) is typically located at the junction of the upper third and the lower two thirds of the thyroid lobes [6]. MTC consists of sheets of spindle-shaped, round or polygonal C cells separated by fibrous stroma [19]. The tumors are usually solitary, strongly hypoechoic, and sharply circumscribed with a homogeneous echo pattern, except for centrally located calcifications that may be of the micro type. They may, however, be more coarse than the calcifications found in papillary carcinomas [6,10]. The same type of calcifications are often found in regional lymph node metastases [(6,7].
