摘　　要：目的探讨甲状腺滤泡状癌(FC)与甲状腺滤泡状腺瘤(FA)的超声学影像特征,以对其进行正确诊断及鉴别诊断。方法回顾性分析经手术病理证实的25例FC和58例FA的临床及超声学影像资料,分析肿瘤的最大直径、外周声晕(晕环)、回声高低、回声均匀性、钙化情况和肿瘤结节数量等超声图像特点。以χ2检验分析FC和FA之间超声影像学特征分布的差异。结果实性肿块、低回声、回声结构不均匀、内部无微小钙化、晕环不完整或不规则厚晕等为FC的超声学影像特征。结论超声检查可较好的对FC与FA进行临床诊断及鉴别诊断。Objective The purpose of this study was to determine the sonographic features of thyroid follicular carcinoma in comparison with thyroid follicular adenoma. Methods This retrospective study included 25 pathologically proven follicular carcinomas and 58 follicular adenomas in 83 patients who underwent thyroid surgery. We analyzed the sonographic features of each tumor, including maximum diameter, peripheral halo, echogenicity, echo texture, calcifications, and nodularity. The frequencies of the sonographic features were compared by X2 test between follicular adenomas and carcinomas. Results Predominantly solid contents, hypoechoic echogenicity, a heterogeneous echo texture, the absence of microealcifications, and an uncomplete or irregular thick halo were associated with follicular carcinoma. Conclusion Sonography could provide useful information for differentiating follicular carcinoma from follicular adenoma.
