Cystic Wilms Tumor

Wilms tumor is the most common pediatric renal malignancy. Patients are typically diagnosed at 3-4 years of age. The tumor arises from nephrogenic rests. Approximately 10% of patients with Wilms tumor have an underlying genetic predisposition. Imaging, including CT, MRI, and abdominal ultrasonography, play a crucial role in diagnosing Wilms tumor. Treatment involves a combination of surgery, chemotherapy, and radiation therapy. The prognosis of Wilms tumor is generally good, although relapse can occur in 20% of patients.
