超声对甲状腺乳头状腺瘤与甲状腺癌的诊断分析

The diagnosis and analysis of thyroid papillary adenoma(PAT) and thyroid cancer by ultrasound

目的:分析超声对甲状腺乳头状腺瘤与甲状腺癌的诊断及鉴别诊断。方法:对13例甲状腺乳头状腺瘤患者与21例甲状腺癌患者的声像图进行分析,所用病例经手术、病理证实。结果:超声显示甲状腺乳头状腺瘤包膜完整,无回声内可见乳头状突起,其内及周边有丰富低速血流信号;甲状腺癌肿块无完整包膜,边界模糊,有的呈“蟹足样”改变,内可见细小成簇钙化点,有的肿块内可伴液化,瘤体内及周边见条状高速血流信号。结论:超声检查尤其是彩色及频谱多普勒对甲状腺乳头状腺瘤及甲状腺癌的诊断及鉴别诊断具有重要价值。

Objective：In order to analysis the diagnosis of ultrasound for the thyroid papillary adenoma and thyroid cancer. Methods： Analyzed among 13 patients who suffered from papillary adenoma of thyroid and 21 patients who suffered from thyroid cancer. All cases were proved by operations and pathology. Results： PAT have complete packing membrane. There is no echo and the nipple in it. There are plenty of low-speed bloodstream signals inside and near it. The thyoid cancers show imeomplete packing membrane. The boundary of tumours is indistinct. Some of turnouts appeared “crablike feet” and minute calcified points can be seen inside of them, as well as some of them in company with liquefaction. Inside and near the turnouts the striped high-speed bloods velocity signals can be seen. Conclusion： Examination by US, especially eolours, and Doppler, to PAT and thyroid cancer, has important value in their diagnosis and discerning diagnosis.
