Clinical value of calcifications in thyroid carcinoma and multinodular goiter.

Background: To confirm the predictive value of calcifications in thyroid nodules as a risk factor for malignancy and to detect aspects specific for tumours.

Materials And Methods: In a set of 196 patients (33 differentiated thyroid carcinoma, 9 follicular adenomas and 154 multinodular goiters with dominant nodule) calcifications were detected by ultrasound scan.

Results: Calcifications were significantly more frequent in differentiated thyroid carcinoma (DTC) than in benign diseases (DTC 39.
