Abstract

Focal nesidioblastosis is a rare cause of endogenous hyperinsulinemic hypoglycemia in adults. Because it is difficult to localize and detect with current imaging modalities, nesidioblastosis is challenging for biliary-pancreatic surgeons. ⁶⁸Gallium-DOTA-D-Phe¹-Tyr³-octreotide PET scanning and ¹¹¹indium-pentetreotide diethylene triamine pentaacetic acid octreotide scanning may be superior to conventional imaging modalities in determining the localization of nesidioblastosis. We report the successful surgical treatment of a 54-year-old woman with focal hyperplasia of the islets of Langerhans, who experienced frequent hypoglycemic symptoms and underwent various diagnostic examinations with different results.
