摘要
目的探讨隐匿性甲状腺癌的高频超声表现及超声诊断价值。方法对26例经手术及病理诊断为隐匿性甲状腺癌病人的超声检查结果进行回顾性分析。结果26例病人共30个癌结节,其中23例为单发结节(88.5%),3例为多发结节(11.5%);癌结节主要表现为低回声,共28个(93.3%);癌结节边缘呈细小毛刺样改变4个(13.3%),癌结节前后径与左右径或上下径的比值大于1者共7个(23.3%),其余两者的比值相近而呈球形或类圆形;癌结节含少许微钙化者8例9个(30.0%),含粗钙化者2例3个(10.0%)。3例3个(10.0%)乳头状甲状腺癌结节可见厚薄不均晕环。颈淋巴结转移2例(7.7%)。彩色多普勒超声显像表现差异较大,脉冲多普勒多显示为高阻的动脉血流频谱。结论高频彩超检查对隐匿性甲状腺癌具有重要的诊断价值。
Objective To evaluate the diagnostic value of Doppler sonography in occult carcinoma of the thyroid （OCT） and its ultrasound fatures. Methods Ultrasonography and clinical data of 26 cases with OCT confirmed by operative pathology were analyzed retrospectively. Results Of the 26 cases, 30 nodules were recorded. In which, 23 cases （88.5%） with solitary nodule, three （ 11.50%） with multiple ones. Twenty-eight nodules （93.30%） showed hypoechoenic; four （ 13.30%） with burr-like edges; seven （23.3%） with longitudinal and transverse ratio L/T〉I, the rest were≈1. Nine nodules （30.0%） indicated minute calcification. Three （10.0 %） showed irregular haloes. Cervical lymph node metastasis was noted in two cases （7.7 %）. The traits of the CDFI were high resistance in the tumor. Conclusion High frequency sonography is of important significance in the diagnosis of OCT.
