【摘要】 目的探讨多层螺旋CT在经典型肾血管平滑肌脂肪瘤中的应用价值。方法回顾性分析24例CT诊断为经典型肾血管平滑肌脂肪瘤的临床和影像学资料。结果 24例患者中男性5例,女性19例;单发病灶19例,单肾多发2例,两肾均为单发1例,两肾均为多发2例。多发者5~13个。病灶多呈圆形、椭圆形或不规则形,8例14个病灶突出于肾包膜轮廓外,余病灶均位于肾实质内。大小:0.4 cm×0.3 cm~6.7 cm×5.9 cm。平扫病灶内富含脂肪(CT值:-106 HU~-10 HU)、多伴索条及软组织密度影。3例增强扫描病灶实性成分多不均匀强化。结论 CT易于发现经典型肾血管平滑肌脂肪瘤中的脂肪成分,可用于定期影像学随访及术前评估。更多还原

【Abstract】 Objective To explore the application value of multislice spiral CT in typical renal angiomyolipoma. Methods A retrospective analysis of clinical and imaging data of 24 patients with classic type renal angiomyolipoma diagnosed by CT. Results Of all the 24 patients,5 patients were male,19 patients were female. Single lesion in 19 cases, multiple lesions within the single kidney in 2 cases, each kidney had a lesion in 1 case, multiple lesions in the both kidneys in 2 cases. The numbers in the multiple lesions:5~13. The lesions were round, oval or irregular in shape, 14 lesions in 8 cases were protruding from the renal capsule outline, the residual lesions were located in the renal parenchyma.Size:0.4 cm×0.3 cm~6.7 cm× 5.9 cm. Unenhanced CT showed the lesions were rich in fat(CT value:-106HU~-10 HU), and more with streaks and soft tissue density. 3 cases underwent enhanced CT,which showed heterogeneous enhancemen in the substantive component of the lesions. Conclusion CT is easy to demonstrate gross fat within the angiomyolipoma, and can be used for regular imaging follow-up and preoperative evaluation.更多还原
