MRI is preferred in infants (<2 years) to avoid radiation and better define nephrogenic rests.
Several other pediatric renal tumors must be distinguished from Wilms tumor:
Key genetic factors include the WT1 gene located on chromosome 11p13. Mutations in this gene are frequently linked to syndromes such as WAGR (Wilms tumor, Aniridia, Genitourinary anomalies, and Range of intellectual disabilities) and Denys-Drash syndrome. Another important locus is 11p15, associated with Beckwith-Wiedemann syndrome, a condition characterized by overgrowth and an increased risk of embryonic tumors. Clinical Presentation

Wilms tumor arises from abnormal renal development containing metanephric blastema. It is a major success story in pediatric oncology, with overall survival rates rising from less than 30% in the mid-20th century to due to multidisciplinary clinical trials. Key Epidemiological Facts
provides excellent visual data on calcifications and vascular invasion. : The NCBI Bookshelf on Histology
: Initial choice. Evaluates mass origin, patency of the inferior vena cava (IVC), and the contralateral kidney. 5. Diagnostic Workup
: Upfront surgical resection followed by stage-adapted chemotherapy.
Mandatory biopsying of regional lymph nodes to ensure accurate staging.
: Standard for low-stage, favorable histology tumors.
⚠️ Palpation of the abdomen must be performed very gently . Forceful manipulation can rupture the delicate tumor capsule, spilling tumor cells into the peritoneal cavity and immediately upgrading the staging to Stage III. 5. Diagnostic Workup
