肾血管平滑肌脂肪瘤亦称良性间叶瘤或错构瘤,是一种较为少见的肾脏良性肿瘤。因其症状表现不一,临床上常被误诊为肾脏恶性肿瘤。我院自1980～1986年1月共收治7例,大部分病人术前未能确诊,仅1例疑为本病,1例经CT扫描确诊,全部病例均经术后病理切片确诊。 Renal vascular smooth muscle lipoma, also known as benign mesenchymal or hamartoma, is a relatively rare renal benign tumor. Because of its different symptoms, clinically misdiagnosed as renal cancer. In our hospital from 1980 to January 1986, a total of 7 cases were treated, most of the patients were not diagnosed preoperatively, only 1 suspected this disease, 1 case was confirmed by CT scan, all cases were confirmed by postoperative pathology.
