AbstractA 37-year-old active duty male Air Force instructor pilot, with no prior medical history, was found unresponsive at his home after awakening with symptoms of altered mental status when the Emergency Medical Service (EMS) was called. The patient was found to be hypoglycemic with a glucose of 37 mg/dL. The patient recovered after administration of a dextrose bolus. Further investigation revealed that over the last several years, the patient exhibited symptoms of lightheadedness and tremors if fasted greater than 3 hours. Further clinical workup strongly suggested the presence of a neuroendocrine tumor. Initial imaging studies to include a multiphasic dedicated pancreatic computed tomography (CT) scan did not demonstrate a pancreatic lesion. However, the utilization of an innovative new nuclear medicine imaging modality, a 68Ga-Dotatate PET/CT, clearly demonstrated a 19 × 16 mm lesion of the distal pancreatic tail, which guided surgical resection. He underwent a robotic-assisted laparoscopic distal pancreatectomy, pathologically characterized as an insulinoma. The patient's symptoms immediately resolved with no recurrence over the next 6 months. The pilot was granted a waiver, returning him to his flying duties. The 68Ga-Dotatate PET/CT enabled the identification of an otherwise occult pancreatic neuroendocrine tumor ultimately leading to this patient's definitive cure and the salvage of this military asset's aviation career.Published by Oxford University Press on behalf of the Association of Military Surgeons of the United States 2020.
