目的探讨结节性甲状腺肿合并甲状腺癌的超声特征及超声诊断价值。方法回顾性分析26例经术后病理诊断为结节性甲状腺肿合并甲状腺癌患者的声像图特征及诊断准确性。超声观察研究的内容包括形态、边界、回声、数目、大小、内部血流情况、阻力指数。结果甲状腺癌的特征性声像图表现有形态上纵径大于横径、低回声、微小钙化、边界欠清、结节内部血流信号较丰富。结节性甲状腺肿合并甲状腺癌占甲状腺结节性病变的2.15%(26/1205);术前超声检查提示甲状腺癌病变的19例,超声诊断符合率为73.1%(19/26),误诊率为26.9%(7/26)。结论结节性甲状腺肿合并甲状腺癌声像图具有一定的特征,超声检查有较高的诊断价值。对高度可疑病例建议超声引导下穿刺活检及病理检查,以明确诊断和为临床合理地选择外科手术时机提供较大的帮助。
Objective To investigate the echocardiographic features and diagnostic value of nodular goiter complicated with thyroid cancer. Methods A retrospective analysis of 26 cases of postoperative pathological diagnosis of nodular goiter with thyroid cancer in patients with sonographic features and diagnostic accuracy. Ultrasound observations include morphology, boundary, echo, number, size, internal blood flow, resistance index. Results The characteristic ultrasonographic features of thyroid carcinoma showed that the longitudinal diameter of thyroid carcinoma was larger than that of transverse diameter, hypoechoic, microcalcification and the boundary was not clear. The signal of internal blood flow in nodules was rich. Nodular goiter with thyroid cancer accounted for 2.15% (26/1205) of thyroid nodular lesions; preoperative ultrasound examination showed 19 cases of thyroid cancer lesions, the diagnostic accuracy of ultrasound was 73.1% (19/26), the misdiagnosis rate 26.9% (7/26). Conclusion Nodular goiter with thyroid cancer sonographic features have certain characteristics, ultrasound has a high diagnostic value. Ultrasound-guided biopsy and pathological examination of highly suspicious cases are suggested to provide a clear diagnosis and provide more help for choosing the timing of surgery reasonably.
