Evaluating the Degree of Conformity of Papillary Carcinoma and Follicular Carcinoma to the Reported Ultrasonographic Findings of Malignant Thyroid Tumor

Abstract

The previously reported ultrasonography findings of malignant thyroid tumor are in conformity with most of the papillary carcinomas, but not with follicular carcinomas. The current ultrasonographic features for thyroid malignancy should be cautiously applied as the indication for needle aspiration biopsy so that follicular carcinomas are not missed by too narrow and strict biopsy criteria.
