[Vascularized renal neoplasms: does the angiographic study enable the differential diagnosis? Cluster analysis of 65 cases].

65 selective renal arteriographies showing vascularized renal tumors are reviewed and a series of 18 parameters is collected. By means of an unusual statistical analysis, the significance of the presence of such parameters in the various histological kinds of tumors is verified in order to find out whether patterns of arteriographic signs permitting a sure differential diagnosis exist. Finally, the present role of arteriography in the diagnostic iter of renal masses is discussed.
