Renal angiomyolipoma is usually regarded as a benign lesion with no malignant potential. This report is of a patient with aggressive renal angiomyolipoma with renal vein and inferior vena cava invasion in a middle-aged female. The imaging findings and the clinical utility of contrast enhanced multi-slice computed tomography and magnetic resonance imaging are discussed. (J HK Coll Radiol 2002;5:240-242)
