In pediatric populations, what age range is nephroblastoma most commonly diagnosed?

• A. Under 5 years
• B. 5-10 years
• C. 10-15 years
• D. Adults

Answer: (A)

Wilms tumor is the most common renal malignancy in children and is most often diagnosed in early childhood. The majority of cases occur before age five, with a peak around two to four years. This makes the under-five age range the best fit for nephroblastoma. In older children and adults, other renal tumors become more likely. Recognizing this age pattern helps differentiate Wilms tumor from other pediatric renal masses and guides imaging interpretation and management.
