Abstract

A 61-year-old man, with a history of prior clear cell renal cell carcinoma in remission, was referred to Ga-DOTATATE PET/CT for the further evaluation of pancreatic tail mass. Ga-DOTATATE PET/CT showed pathologically intense uptake on the pancreatic mass; subsequent biopsy of the pancreatic mass confirmed the diagnosis of clear cell renal cell carcinoma metastasis. Ga-DOTATATE uptake is not specific for neuroendocrine tumors. In the presence of prior malignancy, it should be kept in mind that malignancies apart from neuroendocrine tumors express somatostatin receptors, and they can show Ga-DOTATATE uptake.

摘要

一位 61 岁男性，既往有缓解的透明细胞肾细胞癌病史，因胰腺尾部肿块就诊于 Ga-DOTATATE PET/CT 以进一步评估。Ga-DOTATATE PET/CT 显示胰腺肿块病理性摄取增强；随后对胰腺肿块进行活检证实了透明细胞肾细胞癌转移的诊断。Ga-DOTATATE 摄取对神经内分泌肿瘤并不特异。在存在既往恶性肿瘤的情况下，应该记住除了神经内分泌肿瘤之外的恶性肿瘤也表达生长抑素受体，并且它们可以显示 Ga-DOTATATE 摄取。
