【摘要】 目的探讨甲状腺滤泡型乳头状癌的超声特征,提高超声诊断的准确率。方法对40例经手术及病理诊断为甲状腺滤泡型乳头状癌的声像图特点进行研究。同时选取同期45例甲状腺良性病变作为对照。结果甲状腺滤泡型乳头状癌的超声表现与甲状腺良性结节对比,其超声表现为实性结节(97.2%)、形态不规则(52.8%)、微小钙化(19.4%)、低回声结节(83.4%)及探及肿大淋巴结(25.0%)。良恶性结节的各征象对比均有统计学差异(P<0.005)。Logistic回归多因素分析显示,回声(OR=3.13,95%CI:1.58~6.19)和微小钙化(OR=2.03,95%CI:1.19~3.48)是诊断甲状腺滤泡型乳头状癌的独立性预测因素。结论甲状腺滤泡型乳头状癌的超声声像图表现存在很大的差异性,只有在充分了解了其超声表现特征的前提下,才能提高其诊断的准确率。更多还原

【Abstract】 Objective To study the ultrasonic features of thyroid follicular papillary carcinoma,and to improve the accuracy of ultrasonic diagnosis. Methods The ultrasonographic features of 40 patients with thyroid follicular papillary carcinoma were studied. 45 cases of thyroid benign lesions was the control group. Results The ultrasonic manifestation of thyroid follicular papillary carcinoma compared with benign thyroid nodules,the sonographic manifestation in the solid nodules was 97. 2%,irregular shape was 52. 8%,minute calcification was 19. 4%,low echo nodules was 83. 4% and the agent and swollen lymph nodes was25. 0%. The signs between benign and malignant nodules had statistical difference( P < 0. 005). Logistic regression analysis of multiple factors showed that echo( OR = 3. 13,95% CI: 1. 58 ~ 6. 19) and small calcification( OR = 2. 03,95% CI: 1. 19 ~ 3. 48)were independent predictors for the diagnosis of thyroid follicular papillary carcinoma. Conclusion The ultrasonographic manifestation of thyroid follicular papillary carcinoma is diversified,comprehensive understanding of the ultrasonic characteristics can improve its diagnostic accuracy.更多还原
