Figure 2 Composite of non contrast axial MDCT-post contrast corticomedullary and post contrast nephrographic phases reveals poorly enhancing isodense lesion within the renal pelvis exhibiting calcific specks (white arrow) and hypo-attenuating lesion along its lateral aspect (red arrows). Subtle thickening of the urothelial walls is present.
