Combination of Superselective Arterial Embolization and Radiofrequency Ablation for the Treatment of a Giant Renal Angiomyolipoma Complicated with Caval Thrombus

<div>Representative images from the interventions. (a) Digital subtraction angiography (DSA) image after superselective catheterization of the tumor feeders shows relatively few and thin tumoral arteries and a limited tumor blush (arrows). (b) DSA image after embolization shows devascularization of the tumor with preservation of the renal enhancement. (c) Coronal oblique sonographic image during ablation shows the electrode (arrow), which has been advanced into the soft-tissue part of the tumor. Strong echoes (open arrow) caused by tissue vaporization are noted around the electrode tip.</div>
