Neuroblastoma is one of the pediatric cancers that has the most unpredictable evolution. It can metastasize to almost any organ, but intrarenal metastases have never been reported. We report 2 such cases: the first patient had a left adrenal neuroblastoma completely resected 10 months before routine follow up ultrasound and CT scan demonstrated 3 right intrarenal metastases. The second patient was being investigated for a left abdominal mass when one left intrarenal metastasis was found during the same CT scan. An intrarenal mass found during investigation for staging or follow up of neuroblastoma should then be considered as a metastase until proven otherwise.
神经母细胞瘤是小儿癌症中病情发展最难以预测的癌症之一。它几乎可转移至任何器官，但肾内转移此前从未有过报道。我们报告2例此类病例：首例患者在常规随访超声及CT扫描显示右肾内有3处转移灶的10个月前，已将左侧肾上腺神经母细胞瘤完整切除。第二例患者在因左侧腹部肿块接受检查时，同一CT扫描发现左侧肾内有一处转移灶。因此，在对神经母细胞瘤进行分期检查或随访期间发现的肾内肿块，在未得到其他确诊结果之前，应被视为转移瘤。
