超声显示不同类别的钙化在甲状腺结节诊断的价值

Ultrasound shows the value of different types of calcification in the diagnosis of thyroid nodules

目的:探讨超声显示不同类别的钙化在甲状腺结节诊断中的价值。方法:收治行超声检查诊断为甲状腺钙化结节的患者290例,均有细针穿刺细胞学(FNA)检查或手术病理结果作为金标准,分析不同类别钙化在鉴别甲状腺结节良恶性上的价值。结果:290例钙化结节中恶性结节占75.86%,良性结节占24.14%,良恶性比较,差异有统计学意义(P<0.05)。所有钙化结节中微钙化居多,为82.76%,其中恶性79.17%,良性20.83%,差异有统计学意义(P<0.05);混合钙化31例,其中恶性61.29%,良性38.71%,差异有统计学意义(P<0.05)。结论:微钙化及混合钙化对恶性甲状腺结节具有重要的提示作用,粗大钙化及环形钙化需进一步结合其他检查对结节进行判断。

Objective:To investigate the value of different types of calcification in the diagnosis of thyroid nodules by ultrasonography.Methods:290 cases of thyroid calcified nodules diagnosed by ultrasonography were selected.Fine needle aspiration cytology(FNA)or surgical pathology were used as gold standard to analyze the value of different types of calcification in differentiating benign from malignant thyroid nodules.Results:Malignant nodules accounted for 75.86%and benign nodules accounted for 24.14%in 290 cases of calcified nodules.The difference between benign and malignant nodules was statistically significant(P<0.05).Among all calcified nodules,microcalcifications accounted for 82.76%,of which 79.17%were malignant and 20.83%were benign,the difference was statistically significant(P<0.05).There were 31 cases of mixed calcifications,of which 61.29%were malignant and 38.71%(12/31)were benign.Conclusion:Microcalcification and mixed calcification are important indicators of malignant thyroid nodules.Rough calcification and circular calcification need to be further combined with other examinations to judge the nodules.
