1、甲状腺滤泡型乳头状癌超声影像分析射阳县人民医院超声科江苏盐城224300【摘要】目的:分析甲状腺滤泡型乳头状癌(FVPTC)的超声影像表现,为进一步提高该疾病的认知水平和诊断能力。方法:对我科2011年1月-2015年6月间,经彩色多普勒超声检查诊断为FVPTC36例患者的病理及临床质料进行追踪,并对对应患者的超声影像存图回顾分析。结果:36例FVPTC患者的超声表现可分为3种类型:I型5例(13.89%),具备甲状腺乳头状癌的典型超声表现,结节形态不规则,边界不清,内部可呈极低回声,可见微小钙化;II型16例(44.44%),表现为境界较清晰的等回声或低回声结节,其形态不规则,边缘可见成角
2、或分叶,微小钙化较少见;III型15例(41.67%),声像表现形似腺瘤,结节边界清晰且边缘光整,内部为均匀中等回声。与甲状腺良性结节对比,FVPTC超声表现为形态不规则(58.33%),实性结节32例(88.89%),微小钙化7例(19.44%)以及可探及肿大淋巴结8例(22.22%),上述超声特征的显示率要高于甲状腺良性结节,差异有统计学意义(P<0.05),木组患者经病理学验证,超声诊断符合率为72.22%(26/36)。结论:加强对FVPTC超声基础知识的理论学习,掌握其图形形成的病理生理知识、图形特点,才能提高对FVPTC诊断的准确率。【关键词】甲状腺乳头状癌;滤泡型;超声显像技术
