Nephroblastoma or Wilms' tumor is the most common malignant tumor of the kidney in the pediatric population. Metastasis is caused by hematogenous spread. The most common localizations in decreasing order of frequency are lymph nodes, lungs, and liver. The bone is very rarely affected. According to the literature, bone metastases have been described in the iliac bone, skull, and mandible. The vertebral localization was described in 3 cases only, the first 1 in 2009, and the 2 others in 2015 . The goal of our work is to report a very rare case of metastatic vertebral localization of a Wilms' tumor in relapse after treatment; and thus to underline the potential for vertebral and intracanal involvement in nephroblastoma.
肾母细胞瘤或威尔姆斯瘤是儿童人群中最常见的肾脏恶性肿瘤。转移是由血行播散引起的。按频率递减顺序排列，最常见的转移部位是淋巴结、肺和肝。骨骼很少受累。根据文献记载，已有髂骨、颅骨和下颌骨发生骨转移的报道。仅3例报道了椎体转移，第一例于2009年报道，另外两例于2015年报道。我们这项工作的目的是报告1例治疗后复发的威尔姆斯瘤发生椎体转移的罕见病例；从而强调肾母细胞瘤累及椎体和椎管的可能性。
