ABSTRACT Dual-tracer PET/CT with both 18F-FDG and 68Ga-DOTA-conjugated peptides is currently used in clinical routine for characterizing pNET (pancreatic masses suspicious for neuroendocrine tumor). We describe here the case of a 81-year-old man with a pancreatic lesion showing high 68Ga-DOTATOC uptake and mild 18F-FDG avidity, thus suggesting a well-differentiated pNET, which resulted at endoscopic ultrasound-guided fine-needle aspiration to be a clear cell renal cell carcinoma metastasis. In fact, the patient had right nephrectomy for clear cell renal cell carcinoma 27 years earlier. This case puts light on the role of PET/CT with 68Ga-DOTATOC in imaging RCC, a field which deserves to be further explored.
