高频超声探查甲状腺结节内钙化的临床价值

Clinical Use of High Frequency Ultrasound in Thyroid Nodules with Calcification

目的:探讨甲状腺钙化在诊断和鉴别诊断甲状腺结节中的临床意义。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。

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.
