目的：探讨CT在肾血管平滑肌脂肪瘤诊断方面的临床意义。方法：2008年4月-2011年8月收治肾血管平滑肌脂肪瘤患者22例，均进行CT以及增强螺旋扫描，分析CT影像的特征性表现。结果：22例均表现为圆形、类圆形肿块，或有分叶，均为单发，内未见明确钙化；18例为脂肪型，内可见明确脂肪密度；5例未见明确脂肪密度；1例内可见血性密度灶。7例瘤体突出肾脏轮廓之外；15例边界清晰，7例边界欠清；肿瘤直径约1.5～5.4 cm，平均直径3.4 cm。增强扫描后，皮髓分界期除瘤体内部脂肪无明确增强，瘤体内的其他组织增强，随着时间延长，瘤体未见明显快进快出的征象。结论：增强CT扫描对血管平滑肌脂肪瘤的诊断有着重要的意义。

Objective:To investigate the clinical significance of CT in the diagnosis of renal angiomyolipoma.Methods:22 cases with renal angiomyolipoma were selected from April 2008 to August 2011.All cases underwent CT and enhanced spiral scanning, and then we analyzed the characteristics of CT images.Results:All the 22 cases were all isolated showed round,oval or lobulated mass,no clear calcification;18 cases of fat type,clear fat density can be seen in it;5 cases had no clear fat density;in 1 case with bloody density range.7 cases of tumor protruding kidney contour;15 cases with clear boundary,7 cases with boundary less clear;the tumor diameter ranged from 1.5~5.4 cm,and the average diameter was 3.4 cm.Contrast enhanced CT scans,corticomedullary demarcation period without a clear enhancement in addition to fat inside tumor,other organizations in vivo tumor enhancement. With the prolongation of time,there was no obvious signs of being quick at entering and exiting.Conclusion:Enhancement of CT scanning plays an important role in diagnosis of angiomyolipoma.
