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.
