| 摘 要： | 目的：探讨肾血管平滑肌脂肪瘤（renal angiomyolipoma,RAML）的CT征象及鉴别诊断。方法：回顾性分析26例行CT平扫及增强扫描并经手术病理证实为RAML的临床及CT资料,扫描设备为SOMATON SPIRIT双层螺旋CT扫描仪。结果：RAML的CT表现为圆形或类圆形,密度不均匀,有软组织及脂肪等多种成分或以某种成分为主的肿块。2例巨大肿瘤病灶合并出血。增强扫描表现为病灶不同程度强化,脂肪成分不强化,部分病例血管呈条索状和斑点状强化影。结论：典型RAML有其特征性的CT征象,病灶内是否含有脂肪组织是确诊的重要依据,增强扫描肿块内可见条索状斑点状强化影,颇具特征性。巨大肿瘤病灶内可合并出血。
