    Abstract:
    This study examines the accuracy of ultrasonic scanning in the recognition of malignancy in 103 "cold" thyroid nodules. All nodules underwent to surgical ablation and to histopathological examination. 10 nodules were cistic, 72 solid and 21 mixed cistic-solid on echography. None of the cistic nodules showed malignant disease while six carcinomas were present in solid nodules and one (a papillary cancer) in a mixed cistic-solid lesion. However we were unable to find echographic abnormalities pathognomonic for malignancy. Only in one case (an undifferentiated carcinoma which involved adjacent blood vessels) the diagnosis of malignant tumour was made before operation; in the other cases the echo patterns of the carcinomatous nodules were similar to those observed in benign nodules. Similar ultrasonic findings were also seen in the various types of thyroid cancer (3 follicular, 2 papillary, 1 medullary, 1 undifferentiated) a part the papillary carcinoma which appeared as cistic-solid lesion. Our data seem to limit the diagnostic value of echography in the detection of malignant thyroid nodules, nevertheless they confirm the benignancy of echografically cistic nodules.
