Bone is the third most common site of metastasis from upper tract urothelial carcinoma after radical nephroureterectomy. Although bone biopsy is the gold standard for the diagnosis of bone metastases, they can usually be diagnosed on the basis of imaging tests. We describe a case of upper tract urothelial carcinoma after radical nephroureterectomy presenting with a Schmorl node in the third lumbar vertebra, mimicking lytic bone metastasis. Differentiation of bone metastases from Schmorl nodes is essential for the appropriate management of patients with malignancy.
骨是根治性肾输尿管切除术后上尿路尿路上皮癌第三常见的转移部位。虽然骨活检是诊断骨转移的金标准，但通常可根据影像学检查做出诊断。我们描述了1例根治性肾输尿管切除术后的上尿路尿路上皮癌患者，其第三腰椎出现许莫氏结节，酷似溶骨性骨转移。区分骨转移与许莫氏结节对于恶性肿瘤患者的恰当管理至关重要。
