Figure 2.

MRI images of bilateral nephroblastomatosis enhancing the diffuse homogeneity and the rind-like peripheral location of the lesions (a) compared with the heterogeneity and round shape of bilateral WT (b). The left kidney seems suitable to a nephron sparing surgery as the mass arises from the superior pole above the left pedicle (b). Corresponding apparent diffusion coefficient (ADC) maps demonstrate low ADC in both kidneys with nephroblastomatosis (c) but different ADC values between the right solid nephroblastoma and the left cystic tumour (d).
