Rarely children with Wilms' tumor develop spinal cord dysfunction by metastatic spread into the epidural space or the cord parenchyma. In the case reported here, the mechanism of spinal compression was different.
Case report: The authors report the clinical course of a 2-month-old boy with retroperitoneal extrarenal Wilms' tumor below the left kidney, characterized with a spinal cord compression developed through the intervertebral foramina.
Conclusion: Abdominal tumor, usually corresponding to neuroblastoma, may be a nephroblastoma.
