Prostate-Specific Membrane Antigen (PSMA) Avid Pancreatic Neuroendocrine Tumor

Ga-PSMA PET/CT is increasingly used to evaluate recurrent prostatic malignancy due to its high specificity. A 75-year-old man with a previous history of treated prostate cancer 3 years earlier presented with rising prostate-specific antigen (PSA) level and underwent Ga-PSMA PET/CT which demonstrated a PSMA-avid focus in the neck of the pancreas. Triple-phase abdominal CT demonstrated enhancement in the arterial phase and to a lesser extent the venous phase of a soft tissue mass in the neck of the pancreas. Cytological and histopathological examination of the soft tissue mass confirmed a low-grade pancreatic neuroendocrine tumor.
