| 摘 要 目的 总结甲状腺髓样癌（MTC）的超声图像特征，并与甲状腺滤泡性腺瘤（FTA）鉴别。方法 回顾性分析79例MTC患者共85个结节（MTC组）和76例FTA患者共77个结节（FTA组）的临床资料和声像图特征，比较两组在年龄、发病部位、大小、边界、形态、声晕、钙化灶、内部及周边血流等方面的差异。结果 MTC组与FTA组发病年龄比较，差异无统计学意义（P=0.957）；男女发病比例、结节最大径、发病部位比较，差异均有统计学意义（均P=0.000）。超声图像特征方面，两组结节边界、形态、回声、成分、钙化、纵横比、声晕及周边血流比较，差异均有统计学意义（P=0.000、0.000、0.000、0.000、0.010、0.003、0.000、0.000）；结节内部血流间比较差异无统计学意义（P=0.579）。MTC组27例术后发现淋巴结转移。结论 MTC以低回声为主，囊性变较少，声晕厚薄不均，微钙化，内部血流走形紊乱，周边血流不完整等特征。 |

| Abstract: |
| ABSTRACT Objective To analyze the ultrasonographic features of medullary thyroid carcinoma and differentiate it from thyroid follicular adenoma.Methods Retrospective analysis of the ultrasonographic features of 79 MTC patients with 85 nodules，76 FTA patients with 77 nodules as control group，compare the difference between the MTC and FTA in age，location，size，shape，boundary，acoustic halo，calcification，and peripheral blood flow and other aspects.Results MTC group and FTA group compared to the age：differences between the two groups was not statistically significant，P=0.957.There is a significant difference between the gender，P=0.000.The maximum diameter of nodules；there is a significant difference，P=0.000.Distribution of nodule location have significant difference，P=0.000.Comparison of two groups of ultrasound image features：boundary （P=0.000），morphology （P=0.000），echo （P=0.000），component （P=0.000），calcification （P=0.01），aspect ratio （P=0.003），acoustic halo （P=0.000），peripheral blood flow （P=0.000） between the two groups was statistically significant differences.Internal blood flow there was no statistical significance （P=0.579）.Lymph node metastasis was found in 27 cases of MTC.Conclusion MTC has the characteristics of patients with slightly female more than male，compared with FTA，the volume of MTC is less than FTA，the boundary is not clear and irregular in shape to see more，hypoechoic cystic small aspect ratio is less than 1，halo rare and uneven thickness，microcalcification，internal blood flow is disordered，peripheral blood flow is not complete. |
