Abstract:
The aim of this study was to investigate the relationship between morphologic characteristics of the calcifications detected by ultrasound in thyroid nodules and thyroid carcinoma. Morphologic characteristics of the calcifications on pre-operative ultrasound examinations of thyroids were compared with post-operative pathologic diagnoses in 543 patients undergoing thyroid surgery. Calcifications were divided into microcalcifications (≤2 mm) and macrocalcifications (>2 mm), and the latter were divided into eggshell calcifications in a row, eggshell discontinuous calcifications, irregular calcifications and multilayer-like calcifications, labeled types I-V. We found that thyroid microcalcifications and partial macrocalcifications, such as eggshell discontinuous calcifications, and multilayer-like calcifications were associated with thyroid carcinoma. In conclusion, microcalcifications were more commonly found in malignant thyroid nodules, particularly in papillary thyroid carcinoma. Eggshell discontinuous macrocalcifications and multilayer-like macrocalcifications also occurred mainly in malignant nodules.
