摘　　要：目的:探讨CT诊断肝细胞腺瘤的临床价值。方法:回顾性分析临床病理确诊的16例肝细胞腺瘤的CT平扫和增强三期扫描(动脉期、门静脉期和延迟期)的表现。结果:16例肝细胞腺瘤的平扫及增强CT表现如下:病变为单发肿块,大小不等,边界清晰;大部分位于肝脏右叶。平扫多为低或稍低密度,3例病灶内可见囊变及坏死灶,2例病灶内可见脂肪变性。增强扫描:动脉期病灶除囊变、坏死及脂肪变性部分外呈均匀明显强化;门脉期和延迟期病灶呈等密度或略低密度。结论:大多数肝细胞腺瘤的CT(平扫及三期增强)影像能提供重要信息,对定性诊断有一定参考意义;部分表现不典型者,须密切结合临床及其他辅助检查,慎重作出诊断。Objective：To evaluate the predictive value of CT in the diagnosis of liver cell adenoma.Methods：Plain as well as enhanced CT scan images at three different stages including arterial,portal venous phase and delayed phase of 16 cases that were confirmed as liver cell adenoma by pathological examination were retrospectively analyzed.Results：Plain and enhanced CT scan images showed presentation of individual masse at different size with clear borders in the right lobe of liver in most of the 16 cases.Lesions in most plain scan images were at slight low or low-density,cystic lesions and necrosis were shown in 3 cases,and fatty degeneration in 2 cases.Lesions at arterial phase shown in the enhanced scan images were even and enhanced except regions of cystic lesions,necrosis or fatty degeneration,while lesions at the two latter phases were shown as even or with slight low density.Conclusions：CT images of most liver cell adenoma cases（plain and enhanced scan at three different phases） can show detailed information of the lesions thus can help to make diagnosis.For cases with atypical symptoms,other clinical information and laboratory examination should be considered.
