本文报告一位肾细胞癌胰脏转移病患于肾切除术后长期追踪之经验。一位73岁男性21年前因右肾细胞癌接受肾切除术;常规随访的计算机断层扫描（CT）显示胰腺尾部有一个实性肿块，磁共振成像（MRI）显示胰腺头部和尾部有一些肿瘤。患者无症状，对造影剂过敏。因此，我们无法进行造影CT/MRI以进行进一步检查来诊断胰腺肿瘤。我们进行了超声内镜检查（EUS），发现了一个多血管和低回声的肿块，肿瘤组织通过EUS引导下细针穿刺（EUS-FNA）获得。病理诊断显示透明细胞肾细胞癌胰腺转移，这是类似的病理结果，肿瘤组织最初获得肾切除术。EUS-FNA对于一种罕见类型的胰腺肿瘤的明确诊断非常有用。
This report presents our experience with a case of pancreatic metastasis of renal cell carcinoma (RCC) at a long-term follow-up after nephrectomy. A 73-year-old man underwent nephrectomy for right RCC 21 years ago; computed tomography (CT) scanning on routine follow-up revealed a solid mass in the tail of the pancreas, and magnetic resonance imaging (MRI) showed some tumors in the head and tail of the pancreas. The patient was asymptomatic and allergic to contrast medium. Therefore we could not perform contrast CT/MRI for further examination to diagnose pancreatic tumors. We undertook endoscopic ultrasonography (EUS) and detected a hypervascular and low echoic mass; tumor tissues were obtained by EUS-guided fine-needle aspiration (EUS-FNA). Pathological diagnosis revealed pancreatic metastasis of clear cell RCC; this was similar to the pathological findings of tumor tissues initially obtained by nephrectomy. EUS-FNA was extremely useful for the definitive diagnosis of a rare type of pancreatic tumor.
