Renal cell carcinoma (RCC) is an uncommon tumor that rarely metastasizes primarily to the brain. Brain metastases are commonly observed in patients with metastatic RCC, with a reported incidence of 2-17%. The prognosis of brain metastatic RCC is poor. In this carcinoma type, the source is commonly evident. We report a case of a patient with undiagnosed incidental RCC, who presented chronic headache as the first manifestation.

肾细胞癌（RCC）是一种罕见的肿瘤，很少会首先转移至脑部。脑转移在转移性肾细胞癌患者中较为常见，报道的发生率为2%-17%。肾细胞癌脑转移的预后较差。在这种癌症类型中，来源通常很明显。我们报告一例未被诊断出的偶然发现的肾细胞癌患者，其首发表现为慢性头痛。
