Abstract

Abstract: Gallbladder neuroendocrine neoplasms (NENs) are rare tumors of the biliary system. These neoplasms express somatostatin receptors, and hence radiolabeled somatostatin analog 68 Ga-DOTANOC is used as a PET radiotracer in detection and staging. Gallbladder NEN cannot be differentiated from an adenocarcinoma of the gallbladder based on clinical symptoms or routine radiological imaging such as ultrasound or CT. These are either diagnosed postcholecystectomy or after biopsy from primary or metastatic sites. We present a rare case of gallbladder NEN detected on 68 Ga-DOTANOC PET/CT.
