摘　　要：目的甲状腺髓样癌(MTC)比较少见,其超声表现报道较少,本研究评价高频超声对MTC的诊断价值,以提高术前检出率及诊断水平。资料与方法选取2003年1月—2014年12月在盛京医院确诊的54例MTC患者,选取同期性别、年龄相匹配的108例甲状腺乳头状癌(PTC)患者作为对照,比较两组患者的超声图像特点。结果 MTC组肿物内部多见粗钙化,PTC组多见微钙化,差异有统计学意义(P<0.01)。部分MTC组肿物周边有不完整声晕及部分环绕血流信号,内部血流信号多丰富;PTC组周边无声晕及环绕血流信号,内部血流信号显示多样,差异有统计学意义(P<0.05、P<0.01)。MTC组与PTC组多为低回声,边界多清晰,以纵横比≥1较多,两组差异无统计学意义(P>0.05)。结论 MTC具有甲状腺癌的超声特点,高频超声对MTC的定性诊断有一定的帮助。Purpose Medullary thyroid carcinoma（MTC） is relatively rare and there are few reports of the sonographic findings. This study is to evaluate the role of high-frequency sonography in the diagnosis of MTC in order to improve the preoperative diagnosis. Materials and Methods Fifty-four patients with histopathologically confirmed MTC in Shengjing Hospital from January 2003 to December 2014 were retrospectively studied. One hundred and eight sex-and age-matched patients with histopathologically confirmed papillary thyroid carcinomas（PTC） during the same period were enrolled as the control group. The ultrasonic features of the two groups were analyzed and compared. Results Coarse calcification was more frequently in MTC group while micro calcification was more frequently in PTC group, which showed statistical difference（P〈0.01）. Abundant blood supply and periphery echo halo were more frequently associated with MTC than with PTC（P〈0.05）. Tumors showed hypoechoic, clear boundary, and anteroposterior-to-transverse diameter ratio ≥ 1 in both groups, which showed no statistic difference（P〈0.05）. Conclusion MTC show the characteristic ultrasonographic features. High-frequency sonography can contribute to the diagnosis of MTC.
