目的探讨甲状腺滤泡癌、髓样癌的超声声像图特点。方法与病理结果对照,回顾性分析了18例甲状腺滤泡癌和19例髓样癌的二维及彩色多普勒超声特征。结果甲状腺滤泡癌女性多见,其中16例癌结节呈不均匀回声,10例伴有液化或囊性成分,11例伴有钙化,部分占位可见包膜。甲状腺髓样癌男女无发病率明显差异,13例呈不规则实性低回声结节,并伴有散在砂粒状钙化点,12例边界欠清楚,髓样癌结节均无明显包膜及液化,结节内部血供丰富。结论甲状腺滤泡癌、髓样癌各有一定的声像图特点,对其特征的分析有助于甲状腺癌的分型诊断。
Objective To investigate the sonographic features of thyroid follicular and medullary carcinomas. Methods Compared with the pathological results, retrospective analysis of 18 cases of thyroid follicular carcinoma and 19 cases of medullary carcinoma of the two-dimensional and color Doppler ultrasound features. Results There were more women with thyroid follicular carcinoma, of which 16 cases showed inhomogeneous echoes, 10 cases had liquefaction or cystic components, 11 cases had calcification, and some of them had capsules. There was no significant difference in the incidence of medullary thyroid carcinoma between men and women. Thirteen patients presented irregular solid hypoechoic nodules with scattered sand-like calcifications. The borders of 12 cases were unclear. Medullary carcinoma nodules were not significantly enveloped and liquefied. The blood supply inside the nodules is abundant. Conclusion The thyroid follicular and medullary carcinomas have certain features of sonogram. The analysis of their features is helpful for the diagnosis of thyroid cancer.
