Primary sarcomas of the kidney are extremely uncommon and the results of their angiographic study are rarely reported. A study of five cases that were confirmed histologically demonstrates the absence of specific clinical and urographic findings. Arteriographic appearances are variable and not related to the histological type. The poorly vascularized forms are traditionally the most frequent (2 out of 5 cases) but are not fundamentally different from adenocarcinomas. The diagnosis can be suspected, however, when there is an infiltrating peripheral tumor extending well beyond the capsule. The hypovascularized pseudocystic forms raise the same arteriographic problems as the adenocarcinomas. Arteriography can diagnose malignancy, but the diagnosis of sarcoma is usually impossible before operation.
原发性肾肉瘤极为罕见，其血管造影研究结果鲜有报道。一项对五例经组织学确诊病例的研究表明，缺乏特异性的临床和尿路造影表现。动脉造影表现多样，与组织学类型无关。传统上，血管化程度低的类型最为常见（5例中有2例），但与腺癌并无本质区别。然而，当存在浸润性外周肿瘤且延伸至包膜外时，可怀疑该诊断。血管化程度低的假囊肿型与腺癌存在相同的动脉造影问题。动脉造影可诊断恶性肿瘤，但通常在术前无法诊断肉瘤。
