A report of renal artery embolization for hematuria facilitating neoadjuvant chemotherapy in an unresectable malignant renal rhabdoid tumor

Malignant rhabdoid tumor (MRT) of the kidney is a rare pediatric tumor characterized by its aggressive nature and chemoresistance. Our patient had MRT of the right kidney with tumor thrombus in the renal vein, inferior vena cava, and right atrium. He developed transfusionresistant hematuria. This was successfully controlled with right renal artery embolization allowing completion of his neoadjuvant chemotherapy. He then underwent complete resection of the tumor and thrombus avoiding cardiopulmonary bypass.
