超声诊断甲状腺结节钙化的临床意义

目的：探讨超声诊断甲状腺钙化结节在临床诊治中的意义。方法：回顾分析2009年本院进行手术的227例甲状腺结节患者的临床，彩色多谱勒超声和病理资料。结果：227例甲状腺结节中，43例有钙化，占18．94％（43／227）。甲状腺钙化结节存在于各种病理类型，但恶性甲状腺结节钙化率41．38％（12／29），明显高于良性甲状腺结节钙化率15．66％（31／198），差异有显著性（P〈0．005）。在43例存在钙化的甲状腺结节中，微钙化17例，粗钙化26例，微钙化常发生在恶性肿瘤，粗钙化多发生在甲状腺良性病变。结论：彩色多谱勒超声发现甲状腺钙化结节需引起注意，若为微钙化提示甲状腺恶性肿瘤可能性大，应尽早手术治疗，粗钙化提示甲状腺良陆疾病可能性大，需密切随诊观察。

Clinic value of ultrasonographic diagnosis for calcified thyroid nodules

Objective：To evaluate the clinical significance the of uhrasonographic diagnosis for calcified thyroid nodules. Methods ： Total of 227 cases of thyroid nodule patients were operatived in our hospital during 2009. To analyze their clinical informations clinical, and uhrasonography and pathological feature, Results：Calcification was detected in 43 （18.94 % ）thyroid nodules. Calcification was found in all kinds of thyroid pathological types. The pereentage of calcificated nodules in thyroid malignant tumor（41.38% , 12/29） was higher than the percentage of calcificated nodules in thyroid benigned tumor（ 15.66% , 31/198 ） （P 〈 0. 005 ） 17 nodules with microcalcification, 26 nodules with coarse calcification. Microcalcification was often founded carcinoma, coarse calcification was often founded in be- nigned thyroid disease. Conclusion：Detection of mircalcifieation inside thyroid nodules, has a higher significance in the diagnosis of thyroid carcinoma. Patients with coarse calcification inside thyroid nodules, has a clinical significance in the diagnosis of benigned thyroid.
