目的 探讨超声对甲状腺滤泡癌与腺瘤的鉴别诊断价值.方法 选取我院2017年1月至2018年1月收治的经手术病理确诊为甲状腺滤泡癌患者8例(8个结节)和甲状腺腺瘤患者53例(53个结节),回顾性分析所有患者的临床资料,其均实施彩色多普勒超声和常规二维超声诊断.比较分析两种疾病的声像图特征.结果 8例甲状腺滤泡癌患者结节与53例甲状腺腺瘤患者结节对比存在以下特征:无细晕、形态不规则、回声低或极低、边界不清、存在其他甲状腺病变,有微钙化.而两者内部回声均匀性、结节单双发等特征对比差异无统计学意义.结论 甲状腺滤泡癌与腺瘤经超声鉴别诊断后,其声像图具有较多相似特征,而鉴别的重点内容则在于钙化、回声、边界、声晕、结节形态以及有无其他其他甲状腺病变等,因此临床需予以重视.

Objective :To investigate the diagnostic value of high frequency color doppler ultrasonography in medullary thyroid carcinoma (MTC) .Methods :Twenty-six patients with MTC confirmed by postoperative patholo-gy were retrospectively analyzed for a total of 31 nodules ,such as echo ,size ,shape ,border and internal calcifica-tion .Result :Among the 31 nodules ,19 (61 .3% ) were located in the right lobe and 12 (38 .7% ) were on the left ;30 (96 .8% ) were solid hypoechoic ;22 (71 .0% ) irregular shape ;21 (67 .7% ) blurred boundaries ;Twenty (77 .4% ) were calcified.Of the 26 patients ,20 (76 .9% ) had cervical lymph node metastases and 23 (88 .5% ) had elevated calcitonin .Conclusion :Thyroid myeloid carcinoma high frequency color Doppler ultrasound showed irregular shape , blurred solid hypoechoic nodules ,may be associated with small calcification or thick calcification ,high frequency col-or Doppler ultrasound on the thyroid myeloid Cancer has a high diagnostic value .
