ABSTRACT
The authors report on a series of 1,043 fine-needle biopsies of the thyroid performed under US guidance; the patients had been selected for thyroid pathologic conditions. Fifty-two neoplasms were observed (46 papillary carcinomas, 1 medullary carcinoma, 2 follicular carcinomas, and 3 metastases), which had been detected by cytology and confirmed by histology or autopsy. The authors focus on 46 cases of papillary carcinoma their US features were studied which, through a correlation of variables, allow a quick and "safe" recognition of the type of carcinoma (papillary carcinomas account for nearly 60% of thyroid neoplasms). Tumor echogenicity and outline, and the presence/absence of calcifications were evaluated in most cases, papillary carcinomas presented as focal lesions (alone or associated with other goiter lesions), with irregular and blurred outline, no hypo/anechoic halo and, in about 1/3 of the cases, with calcifications and colliquative areas. In 17% of papillary neoplasms, metastases to loco-regional nodes were observable at US; in 3 cases the carcinoma did involve a loco-regional node but there were no US signs suggestive of it. The incidence of neoplasms on the total of fine-needle biopsies is 4.9%, while in a previous series of 3,038 fine-needle biopsies, without US guidance, on clinically detectable lesions, the figure was about 2%.
