摘　　要：目的对比分析甲状腺髓样癌(MTC)与甲状腺滤泡性腺瘤(FTA)的超声图像,探讨MTC的超声图像特征。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;性别比、结节最大径、发病部位比较,差异均有统计学意义(均P<0.05)。声像图特征方面,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(均P<0.05);结节内部血流比较差异无统计学意义。MTC组27例术后发现淋巴结转移。结论MTC的超声图像特征以低回声为主,囊性变较少,声晕厚薄不均,微钙化,内部血流紊乱,周边血流不完整等。Objective To analyze the ultrasonographic features of medullary thyroid carcinoma(MTC)and thyroid follicular adenoma(FTA),and to investigate the ultrasonographic features of MTC. Methods The clinical data and ultrasonographic features of 79 MTC patients with a total of 85 nodules,76 FTA patients with a total of 77 nodules were retrospectively analyzed. The age,location,size,boundary,morphology,calcification,acoustic halo,calcification,internal and peripheral blood flow were compared. Results There was no significant difference in the age of onset between the MTC group and the FTA group.There were significant differences of gender ratio,the largest diameter of nodules,and the location of the disease between the two groups(all P<0.05). In terms of sonographic features,the nodule boundary,morphology,echo, composition,calcification,aspect ratio,acoustic halo and peripheral blood flow between the two groups were statistically significant(all P<0.05).There was no statistical significance of the internal blood flow between the two groups.Lymph node metastasis was found in 27 cases of MTC. Conclusion MTC has the characteristics of mainly low echo,less cystic,halo rare and uneven thickness,microcalcification,disordered internal blood flow,and incomplete peripheral blood flow.
