摘　　要：目的:探讨不典型肝脓肿的CT动态增强表现及其病理基础,提高对肝脓肿及胆管细胞癌的鉴别诊断水平。方法:回顾性分析经手术病理证实的3例不典型肝脓肿的临床资料及CT表现。结果:不典型肝脓肿的CT表现具有多样性,CT平扫病灶呈均匀或不均匀低密度区,形态呈类圆形,边缘模糊或较清楚。增强扫描动脉期病灶呈轻度强化,门静脉期及延迟扫描病灶呈小环状、蜂窝状及不均匀强化,部分形如"花瓣状"改变,类似肝内胆管细胞癌的影像学表现。结论:螺旋CT动态多期增强扫描对鉴别肝内胆管细胞癌与不典型肝脓肿有一定价值。Objective：To investigate the atypical liver abscess of dynamic enhancement CT manifestations and pathologic foundation,improve the liver abscess and bile duct carcinoma in the differential diagnosis of level. Methods：retrospective analysis of the operation and pathology in 3 cases of atypical liver abscess clinical data and CT manifestation.Results：the CT manifestations of atypical liver abscess with diversity：unenhanced CT lesions showed homogeneous or inhomogeneous low density area,circular shape,blurred edges or more clearly. Enhanced arterial lesions enhanced slightly,portal venous phase lesions showed a small annular,honeycomb, petaloid,grid,cluster,with no obvious reinforced low density zone,the delay period lesions still strengthen the performance.The imaging manifestation and bile duct cell carcinoma is similar to.Conclusion：spiral CT dynamic multi phase enhanced scan in differential diagnosis of atypical hepatic abscess and bile duct cancer cells have a certain value.
