title: [Value and limits of different method in diagnosis and differential diagnosis of retroperitoneal tumors within the lymphatic systems (author's transl)].
abstract: The demonstration of retroperitoneal intralymphatic primary or secondary tumors requires a progressive radiological investigation beginning with simple methods and advancing to more complicated ones. Radiological lymphography is a method which is superior due to its ability to demonstrate small structures in lymphatic vessels and lymphnodes. However, the usefulness of lymphography is limited partially to the retroperitoneal lymphatic system and to gross changes. To improve diagnostic accuracy further diagnostic measures are needed, namely intravenous urography, venocavography, lumbar venography of catheter, sonotomography of the upper abdomen and lymphatic scintigraphy. Exstirpation of lymphnodes- possibly by explorative laparotomy- and histopathological examination enables an extact assessment of lymphnodes of microscopical dimension as determination of the tumor type. The value and limits of complementary methods and the criteria for the diagnosis and differential diagnosis of metastatic lymphnodes and lymphoreticular systemic diseases are discussed. The significance of lymphography for evaluation of topographic expansion of pathological lymphnode changes, the further course of the disease and the effect of therapy according to the authors' experience are presented. It is stressed that the value of lymphography in diagnosing the type of disease is limited.
