Diagnostic challenges in a patient with an occult insulinoma:68 Ga‐DOTA‐exendin‐4 PET/CT and 68Ga‐DOTATATE PET/CT

Key Clinical Message Despite growing evidence for GLP‐1R molecular‐based imaging, successful localization of insulinomas may require the use of multiple imaging modalities. Not all benign insulinomas express the GLP‐1R as expected. Our case demonstrates that there is a still an important role for traditional methods for the anatomical localization of an insulinoma.
