Abstract

Herein, we present the case of a 73-year-old man with recurrent pancreatic tumors 20 years postnephrectomy for clear cell renal cell carcinoma (RCC). Imaging studies revealed multiple hypervascular tumors in the pancreas, posing a diagnostic challenge in differentiating RCC metastases from well-differentiated neuroendocrine tumors (NETs). Magnetic resonance imaging (MRI) chemical shift imaging played a pivotal role in suggesting the presence of fat, supporting RCC metastasis. Surgical resection confirmed the diagnosis.

摘要

在此，我们报告一例73岁男性患者，在因透明细胞肾细胞癌（RCC）行肾切除术后20年出现复发性胰腺肿瘤。影像学检查显示胰腺内有多个富血管肿瘤，在鉴别RCC转移瘤与高分化神经内分泌肿瘤（NETs）时面临诊断挑战。磁共振成像（MRI）化学位移成像在提示脂肪存在方面发挥了关键作用，支持RCC转移的诊断。手术切除确诊了该诊断。
