Abstract
The echographic appearance of 19 histologically confirmed malignant thyroid tumours has been analyzed. The value of information by ultrasonography is compared to scintigraphy and fine-needle aspiration biopsy. All patients demonstrated a sonographic pattern of relatively low amplitude, sparse and disordered echoes. Extended thyroid tumours (T2-3) exhibited a serrated marginal border as a sign of the infiltration to the surrounding thyroid tissue. The clinically important separation of solid and cystic nodules can always be made with certainty. Provided that a subtile examination technique is used, ultrasonography can be of great value in choosing the adequate therapy in scintigraphic cold nodules. Diagnostic ultrasound also yields information concerning the reliable and reproducible classification and accurate location of circumscribed thyroid lesions. In all cases, however, the ultrasound pattern did not provide reliable clues as to their histology. A successful differentiation between benign and malignant solid nodules can be obtained only by cytology and histology. Ultrasonography, scintigraphy and aspiration biopsy, therefore, are complementary methods.
