目的探讨高频超声在甲状腺钙化型结节诊断中的价值。方法回顾分析经高频超声检查的228例甲状腺钙化型结节的病例资料及病理结果,将钙化型结节分4型:I型细小砂粒样钙化;II型细小点状钙化灶;III型弧形或条形钙化;IV型囊内光点钙化。结果细小砂粒样钙化在甲状腺癌患者发生率P<0.05,细小砂粒样钙化对于甲状腺微小乳头状癌更有统计学意义(χ2=19.169,P<0.05)。结论细小砂粒样钙化的检出增加了甲状腺钙化结节恶变的可能,高频超声在甲状腺钙化型结节诊断中具有重要的临床价值。
Objective To investigate the value of high-frequency ultrasound in the diagnosis of thyroid calcified nodules. Methods A retrospective analysis of 228 cases of thyroid calcified nodules by high-frequency ultrasound case data and pathological findings, the calcified nodules divided into 4 types: I-type small grit calcification; II-type small punctate calcification; III-type arc Shaped or strip calcification; type IV intracapsular calcification. Results The incidence of small gritty calcification in patients with thyroid cancer was P <0.05. Small gritty calcification was more statistically significant for small papillary thyroid carcinoma (χ2 = 19.169, P <0.05). Conclusion The detection of small gritty calcification increases the possibility of malignant transformation of thyroid calcification nodules. High frequency ultrasound has important clinical value in the diagnosis of thyroid calcified nodules.
