A 35-year-old man with a sporadic AML. Contrast-enhanced CT shows an exophytic, well-enhanced, right renal AML, 64 mm in diameter (a). Right renal angiography before embolization shows tumor staining and tortuous feeding arteries with a microaneurysm (b). Tumor stain and feeding arteries disappear after embolization using microspheres, absolute ethanol, and microcoils (c). Contrast-enhanced CT 2 years after TAE shows marked shrinkage of the embolized tumor with necrotic changes (d)
