Ultrasonographic, arteriographic, and histopathological findings were compared in 45 patients with histologically-confirmed renal cancer. Ultrasound images clearly demonstrate the presence of a mass possessing similar echographic characteristics to those of the renal parenchyma (isoechogenic forms). Images are rarely homogeneous and are usually of a heterogeneous nature, either diffuse or including anechogenic zones (heterogenic lacunar forms). This latter appearance is almost specific for tumor necrosis, but a diffuse heterogenic image may be observed with or without the presence of necrosis. Necrotic cancers, with limited peripheral vascularization, present few diagnostic difficulties during ultrasonographic examination: the appearance is that of a solid mass, isoechogenic in the present series, heterogeneous, and with or without anechogenic zones. No correlation exists between the degree of echographic image alterations and the importance of vascularization, poorly vascularized cancers, of particular histological types, demonstrating hypo or hyper-echogenic changes more frequently than typical adenocarcinomas.
对45例经组织学确诊为肾癌的患者的超声、血管造影和组织病理学检查结果进行了比较。超声图像清晰显示存在一个肿块，其具有与肾实质相似的回声特征（等回声型）。图像很少是均匀的，通常呈异质性，可为弥漫性或包括无回声区（异质性腔隙型）。后一种表现几乎是肿瘤坏死的特征，但无论有无坏死，均可观察到弥漫性异质性图像。坏死性癌的周边血管化有限，在超声检查中诊断困难较少：表现为实性肿块，在本系列中为等回声，异质性，有或无无回声区。超声图像改变程度与血管化程度之间无相关性，特定组织学类型的血管化不良的癌症比典型腺癌更频繁地表现为低回声或高回声改变。
