Radiological and clinical evaluation of twenty neuroblastomas.

The material includes 15 suprarenal and five other retroperitoneal neuroblastomas. All patients were examined by intravenous pyelography which was evaluated with regard to calcification; renal configuration; compression and displacement of the renal pelvis; and renal concentration. It was possible to distinguish between suprarenal and other retroperitoneal neuroblastomas. In five patients the final diagnosis was obtained by selective angiography. Adventitious tumour circulation was not always due to invasion. A brief survey is given of the clinical findings at the time of examination, metastases being present in 75%. Three patients underwent radical surgery, while six were treated conservatively and in 11 patients surgery was either impossible or incomplete. Survival is possible without total removal o the tumour. The survival rate over a five-year period was 30%.
