目的:探讨甲状腺转移癌的超声表现及诊断价值。方法:对10例经超声引导下穿刺活检证实为甲状腺转移癌的超声图像特点进行分析。结果:本组甲状腺转移癌超声图像表现为甲状腺内多结节型、孤立结节型、弥漫钙化灶型、回声不均型,7例合并钙化灶,3例无钙化灶,9例病变区血流信号异常增多。结论:甲状腺转移癌超声表现多样,无特征性,确诊需依靠穿刺活检。
Objective: To investigate the ultrasonographic features and diagnostic value of thyroid metastases. Methods: Ten cases of ultrasonographic features confirmed by thyroid biopsy under the guidance of ultrasound were analyzed. Results: The ultrasonographic images of thyroid metastasis showed multiple nodules in thyroid, isolated nodules, diffuse calcification, heterogeneous echoes, 7 cases with calcification, 3 cases without calcification, and 9 cases with lesion area blood Abnormal increase in the flow signal. Conclusion: The thyroid metastases have various sonographic features and no features. The diagnosis depends on the biopsy.
