肾血管平滑肌脂肪瘤(AML)过去认为是一种少见肾脏良性肿瘤,但近年来,由于B超、CT、MRI的临床应用,发现该病日益增多。该病以往很难与肾癌相鉴别,均在施行肾切除术后才得以确诊。近十余年来,由于B超、CT在临床上的应用日益广泛,绝大多数患者在术前就能做出正确诊断,并在治疗上根据不同情况进行随诊观察或者行保留肾单位的肿瘤切除术。现就我院从1991年5月～2003年8月收治30例肾血管平滑肌脂肪瘤报告如下。1资料与方法1.1临床资料本组30例,男12例,女18例,年龄20～78岁。肿瘤位于右肾12例,左肾13例,双肾5例;单肾多发2例,双肾多发4例,其中1例伴有面部蝶状分布的皮脂腺瘤;
Renal angiomyolipoma (AML) was previously considered to be a rare neoplasm of the kidney, but in recent years, due to the clinical application of B ultrasound, CT, MRI, the disease is found to be increasing. The disease in the past is difficult to differentiate and renal cell carcinoma, were diagnosed after the implementation of nephrectomy. In recent ten years, due to B ultrasound, CT in the clinical application of increasingly widespread, most patients can make the correct diagnosis before surgery, and in the treatment according to different circumstances follow-up observation or line of nephrology retained Tumor resection. Now on our hospital from May 1991 to August 2003 admitted 30 cases of renal vascular smooth muscle lipoma reported as follows. 1 Materials and Methods 1.1 Clinical data The group of 30 patients, 12 males and 18 females, aged 20 to 78 years.
