#2237 99mTc-Colloid Scintigraphy in the Differential Diagnosis of Pancreatic NET

Introduction: An accessory spleen (AS), a benign and congenital condition, is characterized by a small nodule of splenic tissue found outside of the spleen, which can mimic a pancreatic neoplasm (p-NET). 68Ga-PET/CT is used to study lesions suspected for NET, but the radioactive tracer binds also the reticuloendothelial cells, resulting in false positives in case of AS.

#1565 Molecular Imaging of Late Somatostatin Receptor–Positive Metastases of Renal Cell Carcinoma in the Pancreas by Radiolabeled 111In SRS Octreotide Scan : A Rare Differential Diagnosis to Multiple Primary Pancreatic Neuroendocrine Tumors

Introduction: Somatostatin-Receptor Scintigraphy (SRS) has a sensitivity and specificity for pancreatic NETs (pNETs) of 90 and 80% respectively. SRS is indicated as first staging procedure and one of the most sensitive imaging modalities for well-differentiated neuroendocrine tumors, based on imaging of somatostatin receptors (SSRTs).

#1042 The Challenge of Differential Diagnosis of Solid Pancreatic Lesions in Von Hippel-Lindau. Case Report

Introduction: Von Hippel-Lindau (VHL) is an hereditary syndrome, characterized by a predisposition to develop benign and malignant tumors. Pancreatic involvement is present in 35-70% of cases and include cystic (simple cyst, serous cystoadenoma, mucinous tumor or IPMN) and solid lesions (neuroendocrine neoplasm (NEN), metastatic mass or pancreatic adenocarcinoma). Finally, a solid-type serous cystoadenoma (SSCA) has been reported. Differential diagnosis of these lesions may be difficult.

#740 Heterotopic Pancreatic Tissue Located in the Subserosa of the Jejunum: A Case Report

Introduction: Ectopic pancreas is defined as pancreatic tissue in an abnormal location with no ductal, anatomical, neuronal or vascular communication with the main body of the pancreas. The incidence of heterotopic pancreas in autopsy studies is approximately 0.6 - 15%, while the clinical incidence is 1 in 500 laparotomies. Ectopic pancreatic tissue can be present anywhere along the gastrointestinal tract.

#725 Contrast-Enhanced Ultrasonography (CEUS) Predicts the Effectiveness of Anti-Angiogenic Therapies in Patients with Liver Metastases from Neuroendocrine Tumors

Introduction: Liver metastases (LM) from neuroendocrine tumors (NETs) exhibit a typical hypervascular pattern in the arterial phase on CEUS, allowing for a differential diagnosis between NET and non-NET LM. Medical therapy includes agents acting on angiogenesis and vascularization which may result in a change in CEUS findings.
