Abstract: Abstract: We present a rare case of a 74-year-old woman who underwent 68 Ga-DOTATOC PET/CT imaging for a suspected neuroendocrine tumor (NET) in the pancreatic head. PET/CT showed a solitary high somatostatis receptor (SSTR)-expressing lesion in the pancreatic head. Fine-needle aspiration of this lesion revealed a metastasis from a clear cell renal cell carcinoma (ccRCC). The patient had undergone nephrectomy 16 years prior due to ccRCC of the right kidney. Our case demonstrates that metastases originating from RCC can have high SSTR expression and therefore might mimic well-differentiated neuroendocrine tumors in 68 Ga-DOTATOC PET/CT.<br />Competing Interests: Conflicts of interest and sources of funding: none declared.<br /> (Copyright © 2023 Wolters Kluwer Health, Inc.
