Wilmsי tumor is the most common pediatric renal tumor, but cardiac metastases from this tumor are
rare . An 8-year- old boy presented with hematuria and lower extremity pain. Computed tomography
revealed a left renal mass. In addition, pre-operative echocardiography revealed a large homogenous
mass in the right atrium, extending from the inferior vena cava and protruding through the tricuspid
valve into the right ventricle.
The patient underwent combined radical nephrectomy and removal of the mass from the inferior vena
cava and right heart chambers, followed by immunotherapy. Pathology confirmed undifferentiated
Wilmsי tumor in both the left kidney and the right heart chambers.
The extension of Wilmsי tumor to the great vessels and the heart chambers indirectly affects the final
outcome. It seems in most cases, combination surgery and chemotherapy is the choice method of
treatment, and the selection of chemotherapy or surgery as the primary line of treatment depends on
tumor thrombus extension and the patientי s condition at the time of diagnosis
