增强扫描肿瘤实质部显著强化,坏死区域无强化。结论胃胃肠道平滑肌肉瘤临床及影像学诊断价值[摘要]目的对胃肠道平滑肌肉瘤的临床特征及其影像学诊断情况进行分析和研究。方法回顾分析2014年1月-2016年12月该院接收的手术病理确诊的43例胃肠道平滑肌肉瘤患者的临床资料,分析影像学检查结果,总结临床特征。结果该组43例患者通过X线检查,胃平滑肌肉瘤21例(14例位于腔内,2例腔外,5例合并腔内外);小肠平滑肌肉瘤20例(16例位于腔外,3例腔内,1例合并腔内外),其中14例边缘存在分叶征象,18例存在溃疡表现;2例结肠平滑肌肉瘤,均位于腔内,B超显示腔内实性肿块;CT平扫大多数表现为不规则分叶状态,且内部密度不均,肠道平滑肌肉瘤多发于胃及空肠,且主要是腔内型;小肠平滑肌肉瘤主要是腔外型,综合应用影像学检查能可有效提升诊断准确率。[关键词]胃肠道;平滑肌瘤;影像学诊断[中图分类号]R735[文献标识码]A[文章编号]1674-0742(2017)04(a)-0037-03ClinicalandImagingDiagnosisValueofGastrointestinalLeiomyosarcomaWANGZe-shuangDepartmentofGeneralSurgery,HospitalofNorthernEconomicDevelopmentZone,Rizhao,ShandongProvince,262300China[Abstract]ObjectiveToanalyzeandresearchtheclinicalfeaturesandimagingdiagnosissituationofgastrointestinalleiomyosarcoma・MethodsTheclinicaldataof43casesofpatientswithgastrointestinalleiomyosarcomadiagnosedbytheoperativepathologyadmittedandtreatedinourhospitalfromJanuary2014toDecember2016wereretrospectivelyanalyzedandtheimagingexaminationresultswereanalyzedandtheclinicalfeaturesweresummarized・ResultsInthisgroup,theXrayexaminationshowedthattherewere21caseswithgastrointestinalleiomyosarcoma(14caseswereintracavity,2caseswereextracavityand5caseswereintracavityandextracavity),and20caseswerewithsmallintestinalleiomyosarcoma(16caseswereextracavity,3caseswereintracavityand1casewasintracavityandextracavity),lobulatedsignsoccurredto14cases,ulcermanifestationsoccurredto18cases,colonleiomyosarcomaoccurredto2casesandintracavity,andtheBultrasoundshowedtheintraluminalsolidmasses,mostmanifestationsofCTplainscanshowedtheirregularlobulatedstate,andtheinnerdensitywasuneven,andtheenhancementscanshowedthatthetumorsolidsitewasobviouslyenhancedandtherewasnoenhancementinthenecrosisarea・ConclusionMostofgastrointestinalleiomyosarcomaoccurinthestomachandjejunum,andmostofthemwereoftheintracavitytype,andmostofthesmallintestinalleiomyosarcomawereoftheextracavitytype,andthecomprehensiveapplicationofimagingexaminationcaneffectivelyimprovethediagnosisaccuraterate.[Keywords]Gastrointestinal;Leiomyoma;Imagingdiagnosis胃De道平滑肌肿瘤是临床消化科较为常见的肿瘤病症。近年来,随着人们饮食结构的变化及生活节奏的加快,发病率呈上升趋势,且日益年轻化口]。早期检出并进行及时、有效的治疗,有助于提升患者生存质量,改善预后。传统胃肠道平滑肌肿瘤的临床诊断在肿瘤大小、浸润及转移等方面仍有局限性[2]。随着现代医疗影像学技术的不断发展,有效弥补了这些局限,提升了临床检出率和诊断准确率。该文主要对2014年1月-2046年12月该院收治的43例胃肠道平滑肌肉瘤患者的临床资料及影像学检查结果进行回顾分析,现报道如下。1资料与方法1.1一般资料方便收集该院经手术病理确诊的43例胃肠道平滑肌肉瘤患者的临床资料,并开展回顾性研究。其中,男26例,女仃例;年龄26~81岁,平均(47・5±4・7)岁;病程3个月~5年,平均(1.1±0.3)年;临床表现主要是贫血、便血或者黑便、腹部疼痛、呕血、乏力等,大便潜血阳性42例。1.2方法选用500mA型X光机、D93型数字X线机。该组患者中,21例胃部平滑肌肉瘤患者均实施上消化道常规造影检查;20例小肠平滑肌肉瘤患者均行口服法和插管法小肠双对比造影检查;2例结肠平滑肌肉瘤患者实施顿灌肠造...
