Therapeutic embolization of symptomatic secondary renal tumors

A patient with colic and hematuria from renal involvement with osteogenic sarcoma who was palliated by percutaneous arterial embolization is described. While there has been much experience with embolization of primary renal tumors, this represents the first reported case of therapeutic embolization of a secondary renal tumor. Embolization is recommended as an adjunct to chemotherapy in the poor-risk patient with a symptomatic secondary renal tumor.
