1、肝胆胰外科杂志第26卷第4期Vo1.26No.42014年7月JournalofHepatopancreatobiliarySurgeryJu1.2014论影像学对肝内胆管腺瘤的临床价值胡文超,陈雀芦,敖利,周海滨,都继成,许崇永(1.温州医科大学定理临床学院/温州市中心医院放射科,浙江温州325000;2.温州医科大学附属二院放射科,浙江温州325000)[摘要]目的提高对肝内胆管腺瘤(BDA)的认识。方法对我院收治的1例及文献报告的7例,共8例患者临床及影像学资料进行回顾性分析。结果8例中BDA肿块共1o个(3个肿块1例,i个肿块7例),病灶大小0.4~
2、30mm,肿块均位于肝脏表面,其中位于右肝6个,左肝4个;8例中伴胆管内瘤栓形成I例,伴囊肿I例,伴发肝癌3例。8例中行B超、cT及MR]检查3例,行CT、KRI检查2例,单独行B超检查l例,单独行cT检查2例,3例患者进行了血管造影检查。B超表现为结节状高回声1例,圆形或椭圆形低回声3例;CT平扫表现为低密度影,增强后早期和延迟期均有强化改变4例,平扫呈环状高密度影(钙化性胆管腺瘤),增强扫描表现为环状强化,延迟期强化更明显者1例;MRIT1w呈低信号,T2W呈高信号者3例,Tlw、T2W均呈高或低信号者各1例;3例血管造影检查均显示肿瘤富血供及肿瘤染色改
3、变。结论对位于近肝脏表面的小肿块,CT、MRI平扫加增强扫描对发现和鉴别BDA具有提示作用。[关键词]肝脏;胆管腺瘤;影像诊断[中图分类号]R816.5[文献标识码]A[文章编号]1007—1954(2014)一0297—04TheclinicalvalueofimagingdiagnosisinintrahepaticbileductadenomaHUWen—chao*,CHENQue—lu,AOLi,eta1.*DepartmentofRadiology,DingLiClinicalCollegeofWenzhouMedicalUniversityWhe
