Zhu G, Xie L, Hu X. Diagnosis of pancreatic focal nesidioblastosis assisted by dual‑nuclide tracer positron emission tomography/computed tomography: A case report. Exp Ther Med 2024; 27:42.

Abstract
Nesidioblastosis is a rare cause of hyperinsulinemic hypoglycemia in adults and its clinical features are similar to those of insulinoma with recurrent hypoglycemic attacks. The present study reports the case of a 48-year-old man who visited the Affiliated Hospital of Zunyi Medical University (Zunyi, China) with a 5-year history of recurrent hypoglycemic symptoms such as dizziness and palpitations. Abdominal magnetic resonance imaging (MRI) showed a mass of ~1.2x1.0 cm in the head of the pancreas, which was suspected to be an insulinoma. For confirmation, the patient underwent both fluorine-18-fluorodeoxyglucose (18F-FDG) and gallium-68-labeled 1,4,7,10-tetraazacyclododecane-1,4,7,10-teraacetic acid-d-Phel-Tyr3-Thr8-OC (68Ga-DOTATATE) positron emission tomography/computed tomography (PET/CT), which showed a moderately increased uptake of 18F-FDG but no uptake of 68Ga-DOTATATE in the corresponding lesion. The patient subsequently underwent surgery to remove the lesion, which was pathologically confirmed as a pancreatic nesidioblastosis. This case showed that nesidioblastosis should be considered a differential diagnosis for insulinoma and that dual nuclear tracer PET/CT imaging is helpful for differentiating between the two. If conventional imaging techniques such as ultrasound, CT and MRI cannot identify the cause of hypoglycemia in future cases, dual-nuclide tracer PET/CT imaging should be considered.

Abstract
Differential diagnosis of hypoglycemia in the non-diabetic adult patient is complex and comprises various diseases, including endogenous hyperinsulinism caused by functional β-cell disorders. The latter is also designated as nesidioblastosis or non-insulinoma pancreatogenous hypoglycemia syndrome (NIPHS). Clinically, this rare disease presents with unspecific adrenergic and neuroglycopenic symptoms and is, therefore, often overlooked. A combination of careful clinical assessment, oral glucose tolerance testing, 72 h fasting, sectional and functional imaging, and invasive insulin measurements can lead to the correct diagnosis. Due to a lack of a pathophysiological understanding of the condition, conservative treatment options are limited and mostly ineffective. Therefore, nearly all patients currently undergo surgical resection of parts or the entire pancreas. Consequently, apart from faster diagnosis, more elaborate and less invasive treatment options are needed to relieve the patients from the dangerous and devastating symptoms. Based on a case of a 23-year-old man presenting with this disease in our department, we performed an extensive review of the medical literature dealing with this condition and herein presented a comprehensive discussion of this interesting disease, including all aspects from epidemiology to therapy.

Abstract
Nesidioblastosis is defined as the neoformation of the islets of Langerhans from the pancreatic ductal epithelium and is recognized as the most common cause of hyperinsulinemic hypoglycemia in infants. We herein report an extremely rare case of adult-onset focal nesidioblastosis with the unusual feature of hyperplastic nodular formation. A 55-year-old woman was admitted to our hospital for a tumor detected in the body of the pancreas by magnetic resonance imaging screening. Laboratory examinations showed a high insulin level in the blood. Contrast-enhanced computed tomography and the selective arterial calcium injection test suggested the presence of multiple insulinomas in the body and tail of the pancreas, and, thus, the patient underwent distal pancreatectomy. A histopathological examination of the tumor in the body of the pancreas showed the nodular hyperplasia of islet-like cell clusters. In addition, many small intralobular ductules and islet cells appeared to be budding from the proliferating ductal epithelium, forming “ductuloinsular complexes”. No other abnormal lesion was detected in the remainder of the pancreas. The histopathological diagnosis was focal nesidioblastosis. The patient has remained free of the recurrence of hypoglycemic episodes for more than 31 months. The present case of rare adult-onset focal nesidioblastosis with hyperplastic nodular formation was preoperatively identified as an apparent pancreatic tumor mimicking insulinoma. Nesidioblastosis and insulinoma need to be considered in cases of hyperinsulinemic hypoglycemia, even in adult patients.

Abstract
CASE DESCRIPTION A 6-year-old castrated male Australian Shepherd was evaluated because of a recent onset of persistent hypoglycemia. CLINICAL FINDINGS Physical examination results were generally unremarkable. No abnormalities were detected on thoracic radiographs, and abdominal ultrasonography revealed no obvious pancreatic lesion. Hematologic analysis revealed hypoglycemia with a high serum insulin-to-glucose concentration ratio. TREATMENT AND OUTCOME Insulinoma was suspected; medical treatment with prednisone was initiated, and exploratory laparotomy was performed. No pancreatic lesions or masses were observed. Partial left pancreatectomy and hepatic and local lymph node biopsies were performed. Histologic examination revealed islet cell hypertrophy and hyperplasia, with no evidence of neoplasia. Results of a PCR assay of the pancreatic tissue for Bartonella infection were negative. Clinical, biochemical, and histopathologic findings were compatible with nesidioblastosis. The clinical signs, including hypoglycemia, resolved after surgery. On follow-up examination 8 months later, the dog was apparently healthy and results of a CBC and serum biochemical analysis, including blood glucose concentration, were within respective reference ranges. CLINICAL RELEVANCE To our knowledge, this is the first report of nesidioblastosis in a dog for which clinical signs and clinicopathologic abnormalities resolved after partial pancreatectomy. Although extremely rare, nesidioblastosis should be considered a differential diagnosis in dogs with signs suggestive of insulinoma.

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.

Abstract
BACKGROUND The endogenous hyperinsulinemic hypoglicemia syndrome (EHHS) can be caused by an insulinoma, or less frequently, by nesidioblastosis in the pediatric population, also known as non insulinoma pancreatic hypoglycemic syndrome (NIPHS) in adults. The aim of this paper is to show the strategy for the surgical treatment of ehhs. MATERIAL AND METHODS A total of 19 patients with a final diagnosis of insulinoma or NIPHS who were treated surgically from january 2007 until june 2012 were included. We describe the clinical presentation and preoperative work-up. Emphasis is placed on the surgical technique, complications and long-term follow-up. RESULTS All patients had a positive fasting plasma glucose test. Preoperative localization of the lesions was possible in 89.4% of cases. The most frequent surgery was distal pancreatectomy with spleen preservation (9 cases). Three patients with insulinoma presented with synchronous metastases, which were treated with simultaneous surgery. There was no perioperative mortality and morbidity was 52.6%. Histological analysis revealed that 13 patients (68.4%) had benign insulinoma, 3 malignant insulinoma with liver metastases and 3 with a final diagnosis of SHPNI. Median follow-up was 20 months. All patients diagnosed with benign insulinoma or NIPHS had symptom resolution. CONCLUSION The surgical treatment of EHHS achieves excellent long-term results in the control of hypoglucemic symptoms.

Abstract
We describe a case of a 40 year old patient with recurrent severe fasting and postprandial symptomatic hypoglycemia that occurred 6 years after gastric bypass surgery. The hypoglycemia was associated with increased insulin and C peptide but all diagnostic modalities for localizing an insulinoma were negative. Medical management failed to control symptoms and the patient underwent subtotal pancreatectomy. Surgical tissue examination confirmed the diagnosis of noninsulinoma pancreatogenous hypoglycaemia syndrome (NIPHS) or nesidioblastosis. Initially after surgery the patient had full remission but after 6 months hypoglycemia recurred. However, this time it was well-controlled with octreotide treatment.

Abstract
Introduction We describe a case of diffuse nesidioblastosis in an adult patient who presented with exclusively fasting symptoms and a focal pancreatic 111In-pentetreotide uptake mimicking an insulinoma. Case presentation A 23-year-old Caucasian man had severe daily fasting hypoglycemia with glucose levels below 2mmol/L. Besides rare neuroglycopenic symptoms (confusion, sleepiness), he was largely asymptomatic. His investigations revealed low venous plasma glucose levels, high insulin and C-peptide levels and a 72-hour fast test that were all highly suggestive for an insulinoma. Abdominal computed tomography and magnetic resonance imaging did not reveal any lesions. The sole imagery that was compatible with an insulinoma was a 111In-somatostatin receptor scintigraphy that showed a faint but definite focal tracer between the head and the body of the pancreas. However, this lesion could not be confirmed by endoscopic ultrasonography of the pancreas. Following duodenopancreatectomy, the histological findings were consistent with diffuse nesidioblastosis. Postoperatively, the patient continued to present with fasting hypoglycemia and was successfully treated with diazoxide. Conclusion In the absence of gastrointestinal surgery, nesidioblastosis is very rare in adults. In addition, nesidioblastosis is usually characterized by post-prandial hypoglycemia, whereas this patient presented with fasting hypoglycemia. This case also illustrates the risk for a false positive result of 111In-pentetreotide scintigraphy in the case of nesidioblastosis. Selective arterial calcium stimulation and venous sampling is the most reliable procedure for the positive diagnosis of insulinoma or nesidioblastosis and should be used to confirm any suspicion based on imaging modalities.

Abstract
Surgical treatment is still the only curative treatment proven for patients with neuroendocrine tumors (NET) of the gastroenteropancreatic system. In addition to the therapy of incidental findings, the treatment of NET with variable aggressiveness and often good long-term prognosis requires a thorough preoperative assessment and a surgical procedure that is based on each individual case. Treatment can be surgery alone (if the disease is locally confined) or can be combined with other therapies. Early NET of the stomach and rectum can be cured endoscopically without further diagnostics, while early findings of the appendix can be treated by an appendectomy. Functionally active pancreatic NET and NET of the small intestine are often preoperatively diagnosed based on symptoms. Thus, it is possible to refer the patient to a NET center, if necessary. Stratification of the necessary treatment combination can be made early. An alternative to radical surgical treatment is the operative reduction of the tumor size and hormone production in metastasized NET, which can lead to improved life expectancy and quality of life. Combination with other treatment forms is absolutely necessary in these patients. It has been proven useful to divide the large group of NET based on the different tumor locations, hormone activity, and the degree of differentiation of the tumor. Early forms, locoregionally limited tumor stages, and tumor stages with distant metastases are considered separately.

Abstract
Hypoglycemia due to endogenous hyperinsulinism (EH) is diagnosed in a symptomatic patient with low levels of plasma glucose concomitant with elevated plasma insulin and C-peptide. Causes of EH are pancreatic islet-cells disease, use of insulin secretagogues, and autoimmune hypoglycemia. In this review, the authors studied 24 patients with hypoglycemia due to endogenous hyperinsulinism in order to describe aspects of diagnosis and treatment. Our study demonstrated that after 12 hours of fasting (mini-fasting test; at least three samples), all patients presented the diagnostic criteria for EH. Additionally, we found that 11 of 12 patients (91.7%) who underwent glucagon test achieved glucose levels less than 50 mg/dL and below baseline after 120 minutes. Mini-fasting (3 samples) and glucagon test may be useful to prevent prolonged fasting test to clarify the diagnosis of endogenous hyperinsulinism.

Abstract
Pathologic hyperplasia of various pancreatic endocrine cells is rare but has been long known. β cell hyperplasia contributes to persistent hyperinsulinemic hypoglycemia of infancy, which is commonly caused by mutations in the islet ATP-sensitive potassium channel, and to non-insulinoma pancreatogenous hypoglycemia in adults, which may or may not be associated with bariatric surgery. α cell hyperplasia may cause glucagonoma syndrome or induce pancreatic neuroendocrine tumors. An inactivating mutation of the glucagon receptor causes α cell hyperplasia and asymptomatic hyperglucagonemia. Pancreatic polypeptide cell hyperplasia has been described without a clearly-characterized clinical syndrome and hyperplasia of other endocrine cells inside the pancreas has not been reported to our knowledge. Based on morphological evidence, the main pathogenetic mechanism for pancreatic endocrine cell hyperplasia is increased endocrine cell neogenesis from exocrine ductal epithelium. Pancreatic endocrine cell hyperplasia should be considered in the diagnosis and management of hypoglycemia, elevated islet hormone levels, and pancreatic neuroendocrine tumors. Further studies of pathologic pancreatic endocrine cell hyperplasia will likely yield insights into the pathogenesis and treatment of diabetes and pancreatic neuroendocrine tumors.

Case report: focal nesidioblastosis ("nesidioblastoma") in an adult. Hum Pathol 2009; 41:447-51.

Abstract
Adult nesidioblastosis is an uncommon cause of hyperinsulinemic hypoglycemia characterized by diffuse islet hyperplasia with beta-cell hypertrophy and atypia. The cause of nesidioblastosis in adults is unclear but may be different from nesidioblastosis in infants. In contrast to infants, a focal form of adult nesidioblastosis (ie, "nesidioblastoma") has not been documented, although proposed. We report a 44-year-old man with symptomatic hypoglycemia and localized nesidioblastosis treated with surgical enucleation resulting in normalization of blood glucose. Postoperative euglycemia has persisted in this patient to date (4 months at the time of manuscript submission).

Abstract
This literature review briefly summarizes the epidemiology, pathophysiology, clinical management, and outcomes of patients with pancreatic neuroendocrine tumors (PNETs) and highlights recent advances in PNET research. PNETs are rare neoplasms, compared with carcinomas arising from pancreatic exocrine tissue. They, like other neuroendocrine tumor types, display variable malignant potential, hormone-related syndromes (functionality), localization, and genetic background. Although tumor origin and molecular pathogenesis remain poorly understood, recently established grading and staging systems facilitate patient risk stratification, and thereby directly impact clinical decision making. Although the optimal clinical management of PNETs involves a multidisciplinary approach, surgery remains the only curative treatment for early-stage disease. Surgery may also have a role in patients with advanced-stage disease, including those with hepatic metastases. Alternative therapeutic approaches applied to PNETs, including chemotherapy, radiofrequency ablation, transarterial chemoembolization, biotherapy, polypeptide radionuclide receptor therapy, antiangiogenic therapy, and selective internal radiotherapy, have failed to demonstrate a long-term survival benefit. Surgery remains the primary therapeutic option for patients with PNETs. Research on PNETs is desperately needed to improve the therapeutic options for patients with this disease.

Abstract
OBJECTIVE The aim is to provide guidelines for the evaluation and management of adults with hypoglycemic disorders, including those with diabetes mellitus. EVIDENCE Using the recommendations of the Grading of Recommendations, Assessment, Development and Evaluation (GRADE) system, the quality of evidence is graded very low (plus sign in circle ooo), low (plus sign in circle plus sign in circle oo), moderate (plus sign in circle plus sign in circle plus sign in circle o), or high (plus sign in circle plus sign in circle plus sign in circle plus sign in circle). CONCLUSIONS We recommend evaluation and management of hypoglycemia only in patients in whom Whipple's triad--symptoms, signs, or both consistent with hypoglycemia, a low plasma glucose concentration, and resolution of those symptoms or signs after the plasma glucose concentration is raised--is documented. In patients with hypoglycemia without diabetes mellitus, we recommend the following strategy. First, pursue clinical clues to potential hypoglycemic etiologies--drugs, critical illnesses, hormone deficiencies, nonislet cell tumors. In the absence of these causes, the differential diagnosis narrows to accidental, surreptitious, or even malicious hypoglycemia or endogenous hyperinsulinism. In patients suspected of having endogenous hyperinsulinism, measure plasma glucose, insulin, C-peptide, proinsulin, beta-hydroxybutyrate, and circulating oral hypoglycemic agents during an episode of hypoglycemia and measure insulin antibodies. Insulin or insulin secretagogue treatment of diabetes mellitus is the most common cause of hypoglycemia. We recommend the practice of hypoglycemia risk factor reduction--addressing the issue of hypoglycemia, applying the principles of intensive glycemic therapy, and considering both the conventional risk factors and those indicative of compromised defenses against falling plasma glucose concentrations--in persons with diabetes.

Abstract
BACKGROUND In patients with insulinoma, biochemical proof of inappropriately elevated insulin secretion during hypoglycemia is required prior to surgery. Because circulating insulin levels usually vary widely, we have used the combined OGTT-fasting test to define new normative criteria for a retrospective systematic analysis. METHODS We retrospectively analyzed insulin concentrations from OGTT-fasting tests of 64 patients with surgically removed insulinomas. In addition, the response to intravenous somatostatin infusions was estimated. Normative criteria were defined to obtain comparable estimates of insulin concentrations: basal, glucose-stimulated maximum, postglucose plateau, and secretory bursts. RESULTS Three types of insulin secretion patterns were identified: (1) the autonomous secretion pattern (type 1, N=17) with basal and post-OGTT plateau insulin concentrations of approximately 50 mU/L, suppression after OGTT by 41%, virtual absence of distinctive secretory bursts, and resistance to somatostatin-mediated suppression (25 %); (2) the inadequate suppression pattern (type 2, N=28) with moderately elevated basal and post-OGTT insulin concentrations of approximately 20 mU/L, suppression after OGTT by 73%, absence of secretory bursts, and incomplete somatostatin-induced suppression (56 %); (3) the late-burst secretion pattern (type 3, N=19) with similar basal and post-OGTT insulin concentrations of 17 mU/L, suppression after OGTT by 76%, true insulin bursts of Delta 13+/-11 mU/L (184%), and nearly complete somatostatin-induced suppression by 64%. CONCLUSIONS By means of a new normative analysis of the combined OGTT-fasting test, three different patterns of insulin secretion can be described in patients with insulinoma: the autonomous secretion type, the inadequate suppression type, and the late-burst secretion type.

Abstract
BACKGROUND The persistent hyperinsulinemic hypoglycemia is characterized by clinical symptoms that occur when the blood glucose levels drop below the normal range. Two pathological situations cause this clinical problem: The presence of a tumor of the pancreas secreting excessive amounts of insulin, known as insulinoma, and congenital beta-cell hyperplasia in the pancreas in children and noninsulinoma pancreatogenic hypoglycemia syndrome in adults. PATIENTS AND METHODS Clinical characteristic and surgical outcome of a group of 20 patients operated on for this hypoglycemic syndrome; 18 for insulinoma and two for nesidioblastosis in children was studied. RESULTS eight of the insulinomas were in the head of the pancreas, two in the body, and the remaining eight in the tail. The surgical technique was enucleation in nine cases, local resection in one case because of suspicious malignancy, and distal pancreatectomy in eight cases. Both children with nesidioblastosis underwent 85% pancreatectomy with splenic preservation. There was no mortality in the study, but three patients developed a low-volume pancreatic fistula after head enucleation. CONCLUSIONS Negative results in diagnostic localization together with the small size of the insulinoma represent a poor combination for successful surgery. The intraoperative ultrasonography is the method of choice for the identification of the tumor, as it is able to identify nonpalpable lesions.
