肝脏胆管囊腺癌影像学诊断的价值

目的:探讨彩色多普勒超声和介入超声技术及其他影像学检查在肝脏胆管囊腺癌(HBCAC)诊断中的价值。方法:回顾性分析1995年~2005年6例临床材料完整且经病理证实的HBCAC。结果:HBCAC患者的临床表现和实验室检查缺乏特异性;影像学表现为肝内单发或多发囊性病灶,囊壁明显增厚,囊壁上可见结节回声,囊内探及分隔回声,囊壁及囊内分隔探及血流信号,囊壁结节探及血流信号,无肝内外胆管扩张。二维及彩色多普勒超声和介入超声技术结合CT及MRI对HBCAC的诊断符合率较高。结论:彩色多普勒超声技术应作为诊断HBCAC的首选方法,增强CT、MRI检查、超声引导下穿刺或病灶囊液抽吸涂片检查具有确诊断值。

The diagnosis value of imagic examination in hepatic biliary cystadenocarcinoma

Objective:To evaluate the diagnosis value of color Dopplar and intervention ultrasonography combining other imagic diagnosis in hepatic biliary cystadenocarcinoma(HBCAC).Methods:6 cases with HBCAC confirmed by pathology were analyzed retrospectively.Results:There was no specificity in clinical manifestations and laboratory examination in patients with HBCAC.Imagic appearances of HBCAC were consistent with findings in operation and pathology: there were intrahepatic cystic tumours with thicken wall and nodular,there were intracystic septa in tumours,there were blood flow in the wall,septa and nodular and there were no dilated biliary ducts.The diagnostic value of color Dopplar and intervention ultrasonography combining other imagic examination is higher.Conclusion:Color Dopplar ultrasonography should be first choose for diagnosis of HBCAC.Contrast enhanced CT should be additional method for assessment of blood flow of HBCAC.HBCAC wasn't assessed by Gray scale,color Dopplar ultrasonography and enhanced CT in some cases,contrast enhancement CT,MRI,ultrasound guided biopsy and hydatid fluid smear should be performed.
