[Ultrasonographic appearance of renal cancer. Correlation with arteriographic and histopathologic findings in 45 cases (author's transl)].
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.
