#3947 Heterogeneity of multiple pancreatic neuroendocrine tumors identified by 68Ga-DOTANOC and 68Ga-exendin-4 PET/CT in a patient with endogenous hyperinsulinemic hypoglycaemia and multiple endocrine neoplasia 1

Introduction: Insulinomas are the most frequent functional neuroendocrine tumors of pancreas cause endogenous hyperinsulinemic hypoglycemia (EHH). In about 10% cases, insulinomas are associated with multiple endocrine neoplasia 1 (MEN1).

#3539 A rare presentation of duodenal neuroendocrine carcinoma

Introduction: Duodenal neuroendocrine neoplasms(dNEN) represent 2-3% of all gastro-intestinal NEN.Unlike other midgut NEN,they are usually diagnosed in a localized stage.

#3325 Endoscopic ultrasound elastography in diagnostics of gastroenteropancreatic neuroendocrine tumors

Introduction: An important role of the endoscopic ultrasound (EUS) was found in the diagnostics of neuroendocrine tumors of the gastrointestinal tract (GEP NETs). In recent years, other modalities have been developed which, in combination with the EUS, improve diagnostics and allow prediction of the tumor's biological behaviour. Such methods include elastography (EG). EG is based on demonstrating the difference in tissue stiffness between tumor and reference area.
