[Flaccid paraplegia caused by spinal cord compression disclosing Wilms' tumor in a 12-year-old child].

Flaccid paralysis with spinal cord compression led to discovery of Wilm's tumor with multiple subcutaneous and bone metastases in a 12 year-old child. Intraspinal seeding of Wilm's tumor by hematogenous route or direct extension is extremely rare and usually appears late in the course of therapy. Bone metastases are also rare and are frequently seen in the sarcomatous form of the tumor which involves the vertebral column and differential diagnosis with bone metastasizing renal tumor of childhood (BMRTC) should be considered.
