Twenty-one neoplastic retroperitoneal tumours- in particular Wilm's tumours and neuroblastomas of the suprarenal glands in children - are analyzed angiographically and the significance of the parasitic blood supply evaluated. More than half of the tumours had penetrating or perforating vessels, but in only 50% there were operative and histologic signs of tumour spread into neighbouring structures. The remaining tumours had vascular adhesions. A hint may be the demarcation and the slight vascularity of the tumours. The value of the presence of penetrating or perforating vessels must not be overestimated regarding the spread of the tumour and inoperability.
