Intramedullary spinal cord metastasis is an uncommon manifestation of systemic tumor. We present a case of metastatic mass inside the thoracic spinal cord 6 years after nephrectomy because of renal cell carcinoma. The parenchymal lesion was resected totally and the histologic examination confirmed it as renal cell carcinoma metastasis. The patient's neurological function improved apparently until the intramedullary spinal cord metastasis recurred in situ later. The case shows that renal cell carcinoma has the possibility of metastasis into spinal cord even several years after nephrectomy. Any symptom of neurological deficit should alert to a possible intramedullary spinal cord metastasis.
脊髓髓内转移是系统性肿瘤的一种罕见表现。我们报告一例肾细胞癌肾切除术后6年发生胸段脊髓内转移瘤的病例。对实质性病变进行了全切，组织学检查证实为肾细胞癌转移。患者神经功能明显改善，直到后来脊髓髓内转移在原位复发。该病例表明，肾细胞癌即使在肾切除术后数年仍有可能转移至脊髓。任何神经功能缺损症状都应警惕可能存在脊髓髓内转移。
