[A Case of Pancreatic Metastasis from Renal Cell Carcinoma 16 Years after Left Nephrectomy].

ABSTRACT

A 73-year-old woman underwent left nephrectomy for renal cell carcinoma(RCC). The computed tomography(CT)and magnetic resonance imaging(MRI)revealed a 20-mm tumor in the pancreatic tale showing early enhancement in the arterial phase 16 years after surgery. Fluorodeoxyglucose positron emission tomography(FDG-PET)showed slightly uptake (maximum standard uptake value SUVmax 2.3)and EUS-FNA showed a hyper-vascularized tumor in the pancreatic tail. A single pancreatic metastasis from RCC was diagnosed, and we performed distal pancreatectomy. The histopathological diagnosis was a metastatic pancreatic tumor from RCC. The postoperative course was uneventful and 1 month after surgery, she is alive with no recurrence.
