Renal hemangiomas are rare lesions that demonstrate a spectrum of clinical, radiographic, and pathologic presentation. Angiographic differentiation from renal cell carcinoma is usually possible, and in such cases conservative management should be attempted. Hemangiomas are in some ways similar to arteriovenous malformations, but lack the rapid and pronounced pre-capillary shunting that characterize the latter. Three cases are presented, two managed surgically with one requiring nephroscopy for diagnosis, and one managed non-operatively. Brush biopsies of lesions with pyelographic characteristics of renal hemangioma should not be attempted without prior angiography.
肾血管瘤是一种罕见的病变，具有一系列临床、影像学和病理学表现。通常可以通过血管造影将其与肾细胞癌区分开来，在这种情况下应尝试保守治疗。血管瘤在某些方面与动静脉畸形相似，但缺乏后者所特有的快速且明显的毛细血管前分流。本文报告三例病例，两例接受手术治疗，其中一例需要通过肾镜检查进行诊断，另一例采用非手术治疗。在未先行血管造影的情况下，不应尝试对具有肾血管瘤肾盂造影特征的病变进行刷检活检。
