摘　　要：目的探讨肾上皮样血管平滑肌脂肪瘤(EAML)的CT影像表现,提高对该病的认识和诊断水平.方法收集11例经病理证实为肾EAML的CT影像以及术后病理资料进行回顾性分析.结果11例患者均为单发类圆形或类椭圆形病灶,最大径19.5~92.0 mm;6例病灶与肾实质交界面呈圆弧形,2例呈锥形或尖角状,3例为平直边缘.平扫示9例为稍高密度,2例为等密度;5例强化方式表现为"快进快出",3例为"持续强化",3例为"快进慢出".9例病灶内出现网格状血管强化影.结论肾EAML的CT影像学表现无典型的特异征象,当肾脏单发实性占位CT表现与正常肾实质圆弧形交界面以及网格状血管强化影征象时,应高度考虑EAML的可能.Objective To improve the recognition and diagnosis of the disease by investigating the CT imaging features of renal epithelioid angiomyolipoma(EAML).Methods Pre operative CT images and post-operative pathological datasof 11 cases with renal EAML proved by pathology were collected and analyzed retrospectively.Results All the 11 cases were single round or oval-like lesions with a maximum diameter of 19.5一92.0 mm.The interface between the lesions and renal parenchyma was round in 6 cases,angular in 2 cases and flat in 3 cases.On unenhanced CT images,9 cases showed slightly high density and 2 cases were equal density.The diverse enhancement pattern of all cases was"rapid wash-in to rapid wash-out"in 5 cases,"persistent enhancement"in 3 cases and"rapid wash-in to slow wash out""in 3 cases.Meanwhile,reticular vascular enhancement was found in 9 cases.Conclusion There are no typical specific CT image features for renal EAML.EAML should be highly considered when solitary solid renal tumors showed the signs:the round interface and reticular vascular enhancement.
