【摘要】 目的探讨滤泡型甲状腺乳头状癌(FVPTC)和经典型甲状腺乳头状癌(C-PTC)的超声声像图特征及病理基础。方法收集我院自2009年1月至2015年6月经手术病理证实的40例FVPTC和51例C-PTC的超声影像资料,回顾性分析两组结节的超声声像图特征,并结合病理结果进行对照研究。结果 C-PTC组患者术前超声诊断符合率为85.2%,明显高于FVPTC组的56.1%,差异有统计学意义(P<0.05);FVPTC组与C-PTC组相比,形态规则(47.5%)、边界清晰(60.0%)、等回声(52.5%)、无钙化(52.5%)、有声晕(60.0%)、周边为主型血流(42.5%)及无淋巴结累计(70.0%)在FVPTC组中更常见。形态不规则(51.0%)、边界不清晰(64.7%)、纵横比为≥1(39.2%)、极低回声(41.2%)、微小钙化(49.0%)、无晕(96.1%)、中央为主型血流(54.9%)及淋巴结累计(43.1%)在C-PTC组中更常见。以上特征FVPTC组与C-PTC组结节比较,差异均有统计学意义(P<0.05)。结论与C-PTC相比,FVPTC有更多良性的超声特征,超声可疑恶性特征的缺乏不能排除FVPTC,需对结节结合多个声像图特征综合判断。更多还原

【Abstract】 Objective To investigate the ultrasonic characteristics and pathological findings of follicular variant of papillary thyroid carcinoma(FVPTC) and classical papillary thyroid carcinomas(C-PTC). Methods We reviewed the ultrasound images of 40 patients with FVPTC(FVPTC group) and 51 patients with C-PTC(C-PTC group)confirmed by surgery and pathology in our hospital from January 2009 to June 2015. The ultrasonic characteristics were analyzed retrospectively and compared with pathological results. Results The preoperative correct diagnosis rate of C-PTC group was significantly higher than that of FVPTC group(85.2% vs 56.1%, P<0.05). Regular shapes(47.5%),well-defined margins(60.0%), isoechoic(52.5%), no calcifications(52.5%), presence of sonographic halo(60.0%),predominantly perinodular color Doppler(42.5%) and without lymph nodes metastasis(70.0%) were more frequent in FVPTC group than C-PTC group. Irregular shape(51.0%), ill-defined margin(64.7%), taller-than-wide(39.2%),marked hypoechogenicity(41.2%), microcalcification(49.0%), absence of sonographic halo(96.1%), predominantly internal central color Doppler(54.9%) and with lymph nodes metastasis(43.1%) were more frequent in C-PTC group. The above sonographic features showed statistically significant difference between FVPTC group and C-PTC group(P<0.05). Conclusion Compared with C-PTC, FVPTC have more benign sonographic features. The absence of suspicious malignant features can not exclude FVPTC, and the diagnosis should be made based on multiple sonographic features.更多还原
