摘　　要：目的:探讨脂肪肝背景下肝血管瘤的多层螺旋CT表现特征。方法:回顾性分析本院98例经病理证实的肝血管瘤的影像资料,根据平扫是否有脂肪肝背景分为Ⅰ组(脂肪肝背景),Ⅱ组(无脂肪肝背景且无其他肝脏疾病),再根据CT增强表现分为A组(动脉期边缘结节样强化),B组(动脉期均匀强化),将Ⅰ、Ⅱ组及A、B组进行交叉归类统计分析。结果:肝血管瘤的CT平扫检出率为分别为Ⅰ组58.3%、Ⅱ组84.0%,Ⅰ、Ⅱ组之间差异具有统计学意义;增强CT检查:A组(ⅠA组、ⅡA组)CT增强诊断符合率100%,ⅠB组CT增强诊断符合率22.2%,ⅡB组CT增强诊断符合率88.9%,ⅠB组与ⅡB组之间差异具有统计学意义。结论:脂肪肝背景下,肝血管瘤病灶的相对密度会发生改变,但其强化方式及强化特征仍然符合肝血管瘤的经典诊断标准,对于少数表现不典型病例,则需要结合其他检查来减少误诊率。Objective：To investigate the MSCT features of hepatic hemangioma associated with fatty liver. Methods： The image data of 98 patients with hepatic hemangioma proved by pathology were retrospective analyzed. Through detecting whether they have fatty liver by unenhanced scan, the 98 patients were divided into group Ⅰ （ with fatty liver） and group Ⅱ （ without fatty liver or other liver diseases） , And then, they were assigned to group A （ edge nodular enhancement in arterial phrase） and group B （ homogeneous enhancement in arterial phrase） according to the enhanced CT performance. Cross classification and statistical analysis were processed among group Ⅰ, group Ⅱ and group A, group B. Results： The detection rate of hepatic hemangioma by unenhanced CT scan were 58. 3% （ group Ⅰ） and 84. 0% （ group Ⅱ） respectively. And there was statistical significance between group Ⅰ and group Ⅱ. Enhanced CT scan showed that the diagnostic accordance rate was 100% in group A （ group ⅠA, group ⅡA） , 22.2% in group ⅠB, 88.9%. in group IIB respectively. And there was statistical significance between group IB and group ⅡB. Conclusion： Associated with fatty liver, the relative density of hepatic hemangioma may change. However, the modes and features of its enhancement still accord with typical diagnostic criteria. The combination with other detection is still needed for some untypical cases to reduce misdiagnosis rate.
