多层螺旋CT在肾上腺节细胞神经瘤诊断多层螺旋CT在肾上腺节细胞神经瘤诊断多层螺旋CT在肾上腺节细胞神经瘤诊断多层螺旋CT在肾上腺节细胞神经瘤诊断［摘要］目的分析肾上腺节细胞神经瘤的多层螺旋CT诊断与临床特征。方法对浙江省宁波奉化市中医医院放射科2009年1月〜2013年5月收治的60例肾上腺无功能性肿瘤患者进行回顾性分析。其中肾上腺节细胞神经瘤患者18例，肾上腺无功能腺瘤患者24例,转移瘤8例，无功能嗜络细胞瘤患者10例，共64个病灶。采用LightspeedVCT64层螺旋CT扫描仪对其病灶行平扫及随后30、70s,3min动态增强扫描，并将其影像学表现进行比较分析。结果①肾上腺节细胞瘤形态上大多表现为卵圆形，边界较模糊，密度均匀，有明显的桃尖征，病变部位多以右侧为主，可有钙化的情况出现；②肾上腺节细胞神经瘤在同一扫描或时间点的CT平均值与其他各病变类型比较差异均有统计学意义(P<0.05),其中平扫时表现出密度高于无功能腺瘤，而低于嗜络细胞瘤和转移瘤，而在增强扫描各时间点其密度则表现出明显低于其他各病变类型，羌异均有统计学意义(P<0.05)o结论临床上肾上腺节细胞神经瘤与其他各类型肾上腺无功能肿瘤相比，其多层螺旋CT表现在其病变形态、边界清晰度、肿瘤内钙化、发病部位与平扫CT平均值及增强扫描各时间点CT平均值均有明显的差异性，临床可根据其特点进行鉴别诊断，并为其手术治疗提供影像学依据。［关键词］肾上腺节细胞神经瘤；多层螺旋CT；诊断；临床分析［中图分类号］R736・6［文献标识码］A［文章编号］1673-7210(2014)10(b)-0080-04Applicationofthemulti-slicespiralCTindiagnosisandtreatmentofadrenalganglioneuromaBAOLipinglDAIYajie2LUJian3JIGengsheng3LUOMengjia4WANGLiao51.DepartmentofRadiology,FenghuaHospitalofTraditionalChineseMedicineinNingboCity,ZhejiangProvince,Fenghua315500,China；2.DepartmentofMedicalImage,ZhongshanHospitalAffiliatedtoFudanUniversity,Shanghai200032,China；3.CTDepratment,theFirstPeople'sHospitalofChaohuCity,AnhuiProvince,Chaohu238000,China；4.DepartmentofMedicalImage,theFirstPeople，sHospitalofChangshuCity,JiangsuProvince,Changshu215500,China；5.DepartmentofMedicalImage,theAffiliatedHospitalofNingboUniversity,ZhejiangProvince,Ningbo315020,China[Abstract]ObjectiveToanalyzethediagnosisandclinicalfeaturesofmulti-slicespiralCTinadrenalganglioneuroma・MethodsSixtycasesofpatientswithnonfunctionaladrenaltumoradmittedtoDepartmentofRadiology,FenghuaHospitalofTraditionalChineseMedicineinNingboCityfromJanuary2009toMay2013wereanalyzedretrospectively.Therewere18caseswithadrenalganglioneuroma,24caseswithadrenalnon-functiona.1adenomas,8caseswithmetastatictumors,and10caseswithnonfunctionalcomplextumor,atotalof64focuses・64layersspiralCTseannerofLightspeedVCTtolinescananddynamicenhancedscanof30s,70s,3minwereusedonthefocus,andtheimagingfindingswerecompared.Results①Themorphologyofadrenalganglioneuromamostlycharacterizedbyovoid,fuzzyboundaries,uniformdensity,obviouslypeachtiplevy,morepredominantlyontherightsideofthelesionsite,andhadcalcification；②atthesameaverageCTscanorsamepointscan,theadrenalganglioneuromacomparedwiththeothertypesofpathologicalchangesweresignificantlydifferent(P<0.05),theplainscanshowedthatthedensityofadrenalganglioneuromawashigherthannon-functionaladenoma,andlowerthannonfunctionalcomplextumorandmetastatictumors,butatvariouspointsofenhancedscanitsdensityshowedasignificantlylowerthanotherpathologicaltypes,thedifferenceswerestatisticallysignificant(P<0.05)・ConclusionClinicaladrenalganglioneuromacomparedwithothervariouskindsofnonfunctioningadrenaltumors,theperformanceofmulti-slicespiralCTinitspathologicalchangesshape,boimdarydefinition,calcifica...
