18. (A) An initial nephrotomogram demonstrates a thin
cortical rim surrounding the right kidney (arrows),
reflecting viable renal cortex perfused by perforating
collateral vessels from the renal capsule. (B) Four months
later, a repeat nephrotomogram shows a marked decrease in
the size of the atrophic right kidney (arrowheads).
19. C+ portal venous phase CT demonstrates a wedge of
poorly / non-enhancing renal parenchyma at the upper pole
20. CT demonstrates a non-enhancing
thrombus extending into the renal vein
35. Demonstrates bilateral diffuse calyceal
clubbing (arrows) and deformity
accompanied by thinning of the
adjacent renal parenchyma
(arrowheads)
36. Normal parenchymal thickness in the upper portion of the
kidney and generalized marked parenchymal thinning in the
lower portion. The latter reflects chronic pyelonephritic
scarring secondary to urinary tract infection and
vesicoureteral reflux that occurred in childhood.
43. Normal parenchymal thickness in the upper portion of the
kidney and generalized marked parenchymal thinning in the
lower portion. The latter reflects chronic pyelonephritic
scarring secondary to urinary tract infection and
vesicoureteral reflux that occurred in childhood.
48. (A) An initial nephrotomogram demonstrates a thin
