title: Wilms' Tumor With Intra-Atrial Extension: Treatment and Management.
abstract: Wilms' tumor is the most common renal cancer in children. It can grow for a long time without any characteristic symptoms, causing only fever, abdominal pain, nausea, or vomiting, which is the reason why it is often discovered accidentally. In 1% to 4% of the cases, nephroblastoma leads to complications in the form of intravascular and intra-atrial extension. We present a case of a five-year-old boy with Wilms' tumor extending into the inferior vena cava, right atrium, and then prolapsing through the tricuspid valve into the right ventricle.
