| 摘 要： | 目的通过分析40例术前诊断为肾癌的乏脂肪肾血管平滑肌脂肪瘤的CT影像学特征,以期提高肾脏肿瘤的诊断准确率,减少过度治疗。方法回顾性分析40例术前影像学诊断为肾癌的乏脂肪血管平滑肌脂肪瘤,评价CT平扫及增强后三期扫描中肿瘤的大小、位置、强化模式、强化程度、是否伴有钙化等。结果肿瘤最大径1.6～7.9（3.48±1.68）cm;38例表现为实性占位,2例表现为囊实性占位（BosniakⅣ型）;1例肿瘤伴有钙化;就强化程度而言,13例表现为轻度强化,18例表现为中度强化,9例表现为明显强化;就强化模式而言,28例表现为延迟强化,12例表现为非延迟强化;10例表现为不均匀强化,30例表现为均匀强化。结论 CT强化程度,强化模式及特殊征象在乏脂肪肾血管平滑肌脂肪瘤的诊断中具有一定价值。 |

| Abstract: | Objective To analyze the CT imaging features of renal angiomyolipoma with minimal fat in order to improve the diagnostic accuracy of renal tumors.Methods Forty cases of renal angiomyolipoma with minimal fat were included,which were preoperatively diagnosed as renal cell carcinoma through triphasic helical CT examination.Tumor morphology,topography,homogeneity,enhancement degree,enhancements patterns and presence of intratumoral calcification were evaluated.Results The mean diameter of these forty lesions wa... |
