1、甲状腺滤泡状腺癌与髓样癌彩超表现和病理研究[摘要]目的探讨超声诊断甲状腺滤泡状腺癌和髓样癌的临床应用价值。方法2006年1月〜2012年12月我院共收治甲状腺滤泡状腺癌和髓样癌患者66例,其中甲状腺滤泡状腺癌38例,髓样癌28例,对上述病例分别进行超声检查。结果38例滤泡状甲状腺癌以实质肿块为主(35/38,92.1%),实质肿块表现为等回声(19/35,54.3%)及低回声(16/35,45.7%),边界尚清晰(28例),10例有包膜,不完整低回声晕,未见钙化。甲状腺滤泡状癌的血流分布:0级1例,I级16例,II级8例,I
2、II级13例。血流频谱呈低阻,阻力指数(RI)为0.53〜0.58。甲状腺髓样癌二维声像特征多呈实性低回声,内部分布不均,后方回声衰减,边界不清(14例),无或无完整声晕,结节内可见钙化,特别是沙粒样钙化灶。颈部淋巴结转移多见(71.4%,20/28),且多为双侧。28例患者结节周边及内部均可见较丰富血流信号,周边分布为主,多为断续环状血流,以静脉血流为主,其中0级1例,I级4例,II级6例,III级17例。阻力指数(RI)为0.55〜0.82。结论超声诊断甲状腺滤泡状腺癌和髓样癌具有便捷、高效、无痛、无创的特点,优势明显,
3、通过超声的声像图特征可以较准确评估病变的特征,并结合病理检查结果为甲状腺癌的诊断提供指导依据。[关键词]甲状腺滤泡状腺癌;髓样癌;彩色多普勒超声;病理分类号]R736.1[文献标识码]B[文章编号]2095-0616(2013)22-109-03TheultrasonographyperformanceandpathologicalanalysisofthyroidfollicularcarcinomaandmedullarycarcinomaDONGYunUltrasoundDepartmentofShanxiJincha
