Bilateral renal masses in children are uncommon but can have stakes. Entities such as nephrogenic rests and nephroblastomatosis, bilateral Wilms tumor (Stage V), hereditary renal cell carcinoma associated with von Hippel Lindau and tuberous sclerosis, DICER1 related cystic neoplasms, and lymphoma often overlap in appearance on imaging. Management pathways can differ widely and can range from surveillance to more aggressive surgical managements. Therefore, radiologists need to integrate imaging findings with clinical and genetic clues to protect renal function and optimize outcomes
This exhibit is designed to help participants recognize multimodality imaging features of uncommon bilateral renal masses beyond simple cysts, angiomyolipomas, infection, and metastases. It also highlights key syndromic associations and epidemiology, including WAGR, Denys Drash, Beckwith Wiedemann, von Hippel Lindau, tuberous sclerosis, and DICER1. Finally, it presents a structured, stepwise framework for refining the differential. It guides recommendations for next steps, such as surveillance, biopsy, or chemotherapy first. The approach emphasizes nephron preservation and close collaboration across the care team. Read More
