胆管型肝细胞癌的影像学表现

目的 通过分析胆管型肝细胞癌的影像学表现，提高其诊断水平。方法 临床和病理已证实的胆管型肝细胞癌患12例均经内窥镜逆行胰胆管造影和超声检查。11例又经CT检查。结果 胆管型肝细胞癌病灶在内窥镜逆行胰胆管造影像上表现为形态多样的充盈缺损、卵圆形、烧杯形，而在CT像上，肝内原发肝癌灶同胆管内癌栓具有相同的密度，经病理证实为肝细胞性癌栓。结论 内窥镜逆行胰胆管造影术通常能清晰显示胆管型肝细胞癌灶的形态及胆管内癌栓的形态，结合其他检查如CT与超声以及临床特点可作出正确诊断。

Imaging findings of biliary hepatocellular carcinoma

Objective to improve the diagnostic level of bi liary hepatocellular carcinoma (BHC)through analyzing the imaging find-ings.Methods Twelve patients with clinically and pathologically proved BHC underwen t endoscopic retrograde cholangiop ancreatography(ERCP)and ultrasound(US )examinations.11patients underwen t additional computed tomography(CT)scans.Results On ERCP images,the lesions of BHC presented as multi morphologic filling defects such as ovary and goblet -like images,on CT s cans,intrahepatic lesions of BHC and carcinous emboli within bile ducts presented as similar attenuation which was pathologically demonstrated carcinous em-boli.Conclusion ERCP can usually clearly reveal the morphologies of BHC lesions and carci nous emboli in bile ducts.The integration of ER-CP and other imaging examinations su ch as CT and US as well as clinical characteristics can make correct diagnosis of BHC.[
