甲状腺隐匿癌的超声诊断研究

目的 研究甲状腺隐匿癌的声像图特点,为临床诊治提供有效依据.方法 收集资料完整的甲状腺隐匿癌63例,对肿块特点结合病理学诊断进行对照分析研究.结果 资料显示甲状腺隐匿癌与增生结节或良性肿瘤共存,增生结节或良性肿瘤发生后可以部分癌变,癌变可以从微小的局部发展至很大的肿块.超声提示甲状腺恶性肿块27例均为实质性回声伴钙化点,硬度偏硬,提示错误的11例内部等回声或低回声分布均匀和25例囊实混合回声硬度一般或软.结论 彩超能检出甲状腺微小肿块,作出有价值的诊断.且与其他影像学诊断相比具有一定的优势,因此作者认为超声对甲状腺诊断是首选.

Ultrasound Diagnosis of Thyroid Microcarcinoma

Objective The ultrasound characteristics of thyroid microcarcinoma were studied to find the effective basis of its diagnosis and treatment.Methods 63 cases of thyroid microcarcinoma with complete data were enrolled.The characteristics of thyroid microcarcinoma were studied and compared with pathology.Results Study showed that both microcarcinoma and proliferation node or benign tumor may coexisit in thyroid.Both proliferation node and benign tumor can lead to cancer.The slight local cancer can develop into large masses.27 cases with thyroid malignant tumor diagnosed by ultrasound were the masses with solid echoes,microcalcification and the hardness,but 11 cases with well-distributed isoecho or hypo-echo and 25 cases with mixed-echo and general or soft hardness.Conclusions Ultrasound can detect out the micro-mass of thyroid,and conclude effective diagnosis.Compared with CT and MRI,ultrasound has advantages.Therefore it is the first choice in diagnosing the thyroid.
