目的：提高对少脂性肾血管平滑肌脂肪瘤的认识，探讨其诊治方法。方法回顾性分析经术后病理证实的21例少脂性肾血管平滑肌脂肪瘤的临床特征及影像学表现。结果少脂性肾血管平滑肌脂肪瘤多见于年轻女性，超声显示肿瘤为低回声或等回声，彩色多普勒可见肿瘤内有血流信号。 CT检查21例平扫期未见脂肪样低密度。其平扫CT值36～59 Hu。增强后CT值63～89 Hu。结论少脂性肾血管平滑肌脂肪瘤缺乏特异性的临床症状和体征，对病灶CT的细微分析能够给诊断带来帮助。应谨慎处理肾脏高密度病变以避免不必要的肾脏切除术。

Objective To explore the diagnosis and treatment of renal angiomyolipoma with minimal fat.Methods Totally 21 ca-ses of renal angiomyolipoma with minimal fat were retrospectively reviewed,and the clinical characteristics and image findings were analyzed. Results Renal angiomyolipoma with minimal fat were more common in young women.On ultransonography,the tumors appeared hypoechoic or isoechoic, and showed abundant blood vessels on color Doppler examination.The tumors did not show fat components on CT images.Their atten-uation on unenhanced CT images was 36-59Hu.The enhancement of these tumors was 63-89Hu.Conclusion Renal angiomyolipoma with minimal fat has no specific characteristics on imaging examinations,and can not be reliably identified.Subtle analysis of CT scan was contribute to the diagnosis of renal angiomyolipoma with minimal fat.The homogeneously enhanced hyperattenuated renal lesion should be managed cau-tiously to avoid unnecessary nephrectomy.
