Figure 1: (a) Initial computed tomography scan demonstrating a 5.9 × 5.3 × 6.1 cm heterogeneous mass-like lesion arising from the upper pole of an atrophic right kidney with a single prominent retrocaval lymph node measuring 1.1 cm, with no evidence of further metastatic disease. (b) Repeat computed tomography scan 20 days after the initial computed tomography scan, demonstrating rapid progression of disease. New 0.5 cm × 7.0 cm × 6.8 cm area of cystic change and necrosis within the mass, and local invasion of the renal mass into the right psoas muscle, and the right renal vein abutting the right vena cava with encasement of the solitary right renal artery within the mass
