  		Figure 1. Schematic diagram representing segmental localization of various renal disorders within the nephron. Different components of the nephrons including the glomerulus, proximal convoluted tubule(blue), distal convoluted tubule (green) and collecting duct (yellow) and their associated conditions are demonstrated (courtesy of Robert Chandler, MD, UTHSCSA, San Antonio, TX).

  		Figure 3. Clear cell renal cell carcinoma. Contrast-enhanced CT scan during corticomedullary phase shows a heterogeneous, hypervascular right renal mass (arrows) with areas of necrosis and haemorrhage (arrowhead).

  		Figure 4. (a) Papillary renal cell carcinoma. Contrast-enhanced CT scan during the corticomedullary phase shows a left renal hypoattenuating solid mass (arrow) with foci of calcification (arrowhead). (b) Papillary renal cell carcinoma. Coronal gadolinium-enhanced T1 weighted Gradient echo MRI shows a uniform, hypovascular solid mass (arrow) in the upper pole of the left kidney.

  		Figure 5. Bilateral renal oncocytomas. Delayed phase contrast-enhanced CT scan shows bilateral, hypoattenuating solid renal masses (arrows). While the right renal mass is uniformly hypoattenuating, the left renal mass shows the characteristic central stellate scar (arrowhead).

  		Figure 12. (a) Autosomal dominant polycystic kidney disease complicated by the development of a renal cell carcinoma. Coronal T2 weighted MRI shows innumerable cysts that replace both the kidneys (arrowheads). Incidentally seen is a hypointense mass in the upper pole of the right kidney (arrows). (b) Autosomal dominant polycystic kidney disease complicated by the development of a renal cell carcinoma. Coronal, gadolinium-enhanced T1 weighted two-dimensional GRE MRI shows predominantly peripheral contrast enhancement of the mass in the upper pole of the right kidney (arrowheads).
