摘要
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.
