Right kidney: A large, lobulated, predominantly solid mass lesion with hypodense non-enhancing necrotic areas is seen arising from the inter-polar region of the right kidney.
Left kidney: A large, lobulated, predominantly solid mass lesion with hypodense non-enhancing necrotic areas is also arising from the inter-polar region of the left kidney replacing majority of the left kidney.
Case Discussion
Less than five percent of nephroblastoma cases occur bilaterally.
