Neuroendocrine tumors of pancreas are relatively rare neoplasms and are classified as either functioning or non-functioning tumors. A 55-year-old female diagnosed with a large, well-differentiated, non-functional neuroendocrine carcinoma of pancreas, presented with abdominal pain of increasing severity. A contrast-enhanced examination of the abdomen was performed to reveal a large, diffuse, enhancing pancreatic mass with multiple filling defects within the mesenteric vasculature. We present findings on (68)Ga-labeled [1,4,7,10-tetraazacyclododecane-1,4,7,10-tetraacetic acid]-1-NaI(3)-Octreotide, positron emission tomography-computed tomography ((68)Ga-DOTANOC PET/CT) and the importance of somatostatin receptor-based PET imaging in such patients.
