目的提高肾血管平滑肌脂肪瘤(AML)的术前诊断水平。方法对1989年6月至2003年12月在我院治疗的23例AML病例,从影像诊断的角度统计分析。结果确诊率CT为85%(17/20例),B超为80%(16/20例),静脉肾盂造影(IVP)为0%(0/6例),MRI为83%(8/9例)。结论IVP对诊断AML帮助不大,CT、B超及MRI对AML诊断很有价值。
Objective To improve the preoperative diagnosis of renal angiomyolipoma (AML). Methods Twenty-three cases of AML treated in our hospital from June 1989 to December 2003 were statistically analyzed from the angle of image diagnosis. Results The diagnostic rates were 85% (17/20), 80% (16/20) for B ultrasound, 0% (0/6) for intravenous pyelography (IVP) and 83% (8/9) for MRI example). Conclusion IVP is not helpful in diagnosis of AML. CT, B ultrasound and MRI are valuable in the diagnosis of AML.
