Abstract
A 79-year-old patient with a history of renal cell carcinoma (RCC) presented with nonspecific upper abdominal pain 6 months ago. Contrast-enhanced CT and MRI did not reveal definitive evidence of malignancy. However, 68Ga-LNC1007 (68Ga-FAPI-RGD) PET/CT demonstrated a significant radiotracer-avid focus in the tail of the pancreas, initially interpreted as a metastatic RCC lesion. Surgical pathology later confirmed the lesion as a neuroendocrine neoplasm (NEN). This case illustrates that neuroendocrine tumors may occasionally be missed by conventional imaging modalities or suspected as other malignancies in certain scenarios, and highlights the potential diagnostic value of 68Ga-LNC1007 PET/CT in detecting neuroendocrine tumors.
