The finding of a renal mass on imaging is suggestive of metastatic non-small cell lung cancer in the presence of a lung tumor but can also have another origin.
We describe the case of a patient diagnosed with stage IV lung cancer based on a renal metastasis. A second opinion including review of histopathological data and additional imaging followed by lung surgery and cryoablation of the kidney lesion revealed two tumors of different origins, non-small cell lung cancer and a renal cell carcinoma.
The presence of a renal mass diagnosed on a CT scan in a patient with lung cancer is not always synonymous with metastatic disease. Confirmation of diagnosis by tissue sampling is mandatory, especially if a synchronous primary tumor is possible.
在存在肺部肿瘤的情况下，影像学检查发现肾脏肿块提示转移性非小细胞肺癌，但也可能有其他来源。
我们描述了一例基于肾转移而被诊断为IV期肺癌的患者。通过包括组织病理学数据回顾和额外影像学检查的二次诊断，随后进行肺部手术和肾脏病变冷冻消融，发现了两个不同来源的肿瘤，即非小细胞肺癌和肾细胞癌。
肺癌患者CT扫描诊断出肾脏肿块并不总是意味着转移性疾病。通过组织采样进行诊断确认是必不可少的，特别是如果可能存在同步原发性肿瘤。
