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，III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，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。---本文来源于网络，仅供参考，勿照抄，如有侵权请联系删除---［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)22-109-03TheultrasonographyperformanceandpathologicalanalysisofthyroidfollicularcarcinomaandmedullarycarcinomaDONGYunUltrasoundDepartmentofShanxiJinchaiMachineryManufacturingCo.,Ltd.StaffHospital,Datong037036,China［Abstract］ObjectiveToinvestigatetheclinicalapplicationsvalueofultrasounddiagnosisforthyroidfollicularcarcinomaandmedullarycarcinoma.MethodsFromJanuary2006toDecember2012inourhospital,selected66patientswiththyroidfollicularcarcinomaandmedullarycarcinoma,included38casesofthyroidfollicularcarcinomaand28cases,medullarycarcinomaandabove-mentionedcaseswereacceptedultrasoundexamination.Results38casesoffollicularthyroidcancerweremainlyinrealmass(35/3892.1%)，therealperformancewasmassechogenic(19/35，54.3%)andhypoechoicechogenic(16/35，45.7%)，theborderwasclear(28cases).10caseshadenveloped，---本文来源于网络，仅供参考，勿照抄，如有侵权请联系删除---incompletehypoechoichalo,nocalcification.Thebloodflowdistributionoffollicularthyroidcancer：0gradehad1case,Igradehad16cases,IIgradehad8cases,IIIgradehad13cases.Flowspectrumwaslowresistance,RI=0.53-0.58.Thedimensionalsonographicfeaturesofmedullarythyroidcarcinomamostlyweresolidhypoechoicandinternalunevendistributionandposteriorechoattenuation,nocalcification(14cases),hadnoornofullsounddizzy,andnodulehadcalcification，especiallywassandlikecalcification.Cervicallymphnodemetastasiswasmorecommon(71.4%，20/28)，andmostlywerebilateral.28casesofpatientswithnodularperipheralandinternalflowsignalswereseenmoreabundant,weremainlyperipheraldistribution,mostlyintermittentannularflowtovenousflow-based,where0gradehad1case,Igradehad4cases,IIgradehad6cases,Illgradehad17cases.Resistanceindex(RI)was0.55~0.82.ConclusionUltrasounddiagnosisofthyroidfollicularcarcinomaandmedullarycarcinomahasaconvenient,efficient,painless,non一invasivecharacteristicsadvantages,sonographicfeaturesbyultrasoundcanaccuratelyassesslesioncharacteristics，andcombinedwiththepathologicalfindingstoprovideguidanceforthediagnosisforthyroidcancerbasis.---本文来源于网络，仅供参考，勿照抄，如有侵权请联系删除---[Keywords]Thyroidfollicularcarcinoma...
