4 | CONCLUSION
ERWTs should be considered in the differential diagnosis of children exhibiting a pelvic mass and suffering from hypertension and dilated cardiomyopathy. The clinical symptoms observed in the present case were likely attributable to the secretion of renin by the Wilms tumor. Tumor resection represents a highly effective treatment for affected patients, but ERWTs presenting with CHF and dilated cardiomyopathy are nonetheless life-threatening, underscoring the need for early diagnosis and the timely provision of intensive care and oncological treatment in order to ensure the best possible clinical outcomes.
