Pancreatic Metastases from Renal Cell Carcinoma Showing Atypical Imaging Findings

A 59-year-old man receiving sunitinib chemotherapy for postoperative recurrence of renal cell carcinoma (RCC) metastases was found to have multiple metastases on contrast-enhanced computed tomography (CECT). CECT revealed a typical hyperdense enhanced nodule in the arterial phase of the stomach and...

Description
Summary:A 59-year-old man receiving sunitinib chemotherapy for postoperative recurrence of renal cell carcinoma (RCC) metastases was found to have multiple metastases on contrast-enhanced computed tomography (CECT). CECT revealed a typical hyperdense enhanced nodule in the arterial phase of the stomach and head and tail of the pancreas. However, in the uncinate process of the pancreas, CECT revealed an atypical image and a hypodense enhanced nodule in each phase. Both lesions were finally pathologically diagnosed as clear cell carcinoma. Treatment-modified pancreatic metastases from RCC may present with nonspecific images; therefore, caution is required when deciding on treatment strategies.
