摘　　要：目的探讨肾脏乏脂肪血管平滑肌脂肪瘤的CT特点,以提高其认识。方法回顾性分析2011年3月~2016年10月我院经病理证实的13例肾脏乏脂肪血管平滑肌脂肪瘤的CT表现。结果本组病例中,9个病灶呈类圆形/圆形,9个病灶呈外生型生长;8个病灶与肾实质交界表现为"V"形角征,2个"杯口"样改变;CT平扫8个病灶呈略高密度;肾实质期8个病灶呈均匀强化;6个病灶明显强化,3个病灶中度强化,4个病灶轻度强化;动态增强9个病灶呈持续强化。结论 CT密度、形态、生长方式、强化程度及强化方式有助于肾脏乏脂肪血管平滑肌脂肪瘤的诊断,CT表现有一定的特征。Objective To explore the CT characteristics of renal angiomyolipomas with minimal fat,thereby improving the understanding of this syndrome.Methods The CT findings of 13 cases of renal angiomyolipoma with minimal fat confirmed by surgery and pathology in our hospital from March 2011 to October 2016 were analyzed retrospectively.Results In this group, of cases,9 lesions were nearly-circular or round;9 lesions showed exophytic growth;8 lesions showed the ＂V＂ angle sign with the junction of renal parenchyma junction;＂Cup＂ change was detected with 2 lesions;slightly high den- sity was found with 8 lesions;homogeneous enhancement was found with 8 lesions at renal parenchymal phase;6 lesions showed obvious enhancement,3 lesions showed moderate enhancement,4 lesions showed mild enhancement.Dynamic enhancement in 9 lesions was prolonged.Conclusion CT manifestations of renal angiomyolipomas with minimal fat have certain features.Aside from CT density,morphological characteristics,growth pattern,enhancement level and enhancement pattern of the symptom are helpful for the diagnosis.
