[Radiological diagnostic of retroperitoneal extrarenal tumors in childhood (author's transl)].

This reports about 54 children suffering from retroperitoneal tumors excluding renal tumors. Characteristic radiological findings of neuroblastomas, pheochromocytomas, suprarenal carcinomas, adenomas, and teratomas are discussed. The diagnosis is made by the following roentgenological investigations: intravenous urography via the V. cava as "Cavo-Urography" or infusion urography (including zonography), sonography and nuclear medicine studies. Arteriography, pneumoretroperitoneum and lymphography are indicated if the primary tumor is unknown, in order to reveal suspected metastases, to decide about operability and for controlling radiotherapy. Further radiological examinations are made depending on the type of the metastasis.
