高频超声探查甲状腺结节内钙化的临床价值

目的：探讨甲状腺钙化在诊断和鉴别诊断甲状腺姑节中的临床意义。方法：回顾性分析经超声检查和手术病理证实的77例甲状腺结节患者的临床资料。结果：超声检查与病理对照分析显示：良性20例，结节性甲状腺肿18例，恶性56例，其中乳头状癌50例，乳头状增生1例。良性结节中超声声像图钙化多表现为均匀强回声光斑，光团或弧形光团，后方伴声影。恶性结节中钙化表现为“针尖样”、“砂粒样”、“点状”的微钙化，后方声影可有可无。结论：依据甲状腺结节内钙化的形态大小，可以鉴别甲状腺结节的良恶性。

Clinical Use of High Frequency Ultrasound in Thyroid Nodules with Calcification

Objective To investigate the significance of thyroid calcification for diagnosis of thyroid carcinoma.Methods: Retrospiective analysis of 77 thyroid nodules' pre-operative ultrasonic and postoperative pathologic results.Results: benign nodules 20,calification was macro-calcification while malignant 56,calcification was micro-calcification.Conclusions: Thyroid nodules with calcification especially micro-calcification is considered to be the most specific sign of thyroid crcinoma,so the detection of it should be an important diagnostic criterion.
