目的回顾分析经病理证实的肝内周围型胆管细胞癌的CT影像表现,以提高术前诊断准确率。方法本组17例病例采用PQ-2000S单排螺旋CT平扫及三期增强扫描。结果CT平扫显示肿块呈不规则形态(13例)或类圆形(4例),58.8%患者病灶呈低或稍低密度。增强扫描动脉期病灶无明显强化或边缘轻-中度强化,门静脉期及延迟扫描病灶强化逐渐明显,部分病例有逐渐填充趋势;肿块多合并肝内胆管扩张、肝门淋巴结肿大、附近肝叶萎缩等间接征象。结论肝内周围型胆管细胞癌CT扫描有较特征性影像表现,结合AFP等检查可与肝细胞癌和肝血管瘤等肝内其他占位病变相鉴别。
Objective To retrospectively analyze the CT findings of pathologically confirmed intrahepatic cholangiocarcinoma in order to improve the accuracy of preoperative diagnosis. Methods 17 cases of this group using PQ-2000S single-slice spiral CT and three enhanced scan. Results CT scan showed irregular masses (13 cases) or round (4 cases). 58.8% of patients showed low or low density of lesions. Enhanced arterial phase enhanced scan without significant enhancement of the edge or light - moderate enhancement, portal vein and delayed scan enhancement lesions gradually obvious, in some cases there is a gradual filling trend; mass combined intrahepatic bile duct dilatation, hilar lymphadenopathy, near the liver Atrophy and other indirect signs. Conclusions CT scan of intrahepatic peripheral cholangiocarcinoma has characteristic imaging features. Combined with AFP examination, it can be differentiated from other intrahepatic liver lesions such as hepatocellular carcinoma and hepatic hemangioma.
