#168 Neuroendocrine Tumors - Imaging Abdominal Complications
Introduction: Neuroendocrine tumors mostly arise from the gastrointestinal tract and pancreas but also from bronchopulmonary or any other organ. Abdominal complications are usually associated with the primary GI tract tumor.

#2213 Imaging Modality Depending on the Levels of Tumor Markers
Introduction: 18 F-Fluorodihydroxyphenylalanine(18F)-FDOPA positron emission tomography (PET)/computed tomography (CT) has the advantage of being a noninvasive test and is by far the most promising imaging modality for neuroendocrine tumors (NETs).

#22 A Case Illustrative of Phenotypic Heterogeneity and Challenges in the Management of Paraganglioma
Introduction: Paragangliomas (PGLs) are extra-adrenal, usually benign, highly vascularized tumors that originate from neural-crest-derived chromaffin cells. These tumors are subdivided as either sympathetic or parasympathetic, depending on their location and catecholamine production. Sympathetic PGLs are situated along the abdominal sympathetic trunk and usually produce catecholamines, whereas parasympathetic PGLs are located in the head and neck, and these usually do not produce catecholamines. PGLs may present as sporadic or inherited tumor syndrome, including MEN 2, with RET germline mutations, von Hippel-Lindau (VHL) disease due to germline mutations in VHL gene, and pheochromocytoma-PGL syndrome. The latter is frequently a hereditary condition and is caused by germline mutations in the SDHB, SDHC, or SDHC genes. Patients with familial PGLs may present at a younger age, often as multifocal tumors, with an increased risk of recurrence and a higher frequency of malignancy in those with SDHB mutations. SDH mutations induce angiogenesis and tumorogenesis through the inhibition of hypoxia-inducible factors (HIF)-propyl hyroxylase. A younger age at onset, malignancy, and a positive family history are clinical parameters of high specificity, but low sensitivity for diagnosis. Genetic analysis for mutations in SDH genes for the patient and family members, and surveillance for the affected patient and family members, are necessary where there are no clear clinical or family indicators for the syndrome. We present a case of a large abdominal malignant PGL in a 20-year-old pt. that went on without clinical detection for at least three years.

#59 Incidence and clinical significance of adrenal masses in patients with gastrenteropancreatic neuroendocrine tumors
Introduction: The widespread application of modern imaging modalities, mainly computerized tomography (CT) and magnetic resonance imaging (MRI), has revealed a 2-3% incidence of inadvertently discovered adrenal masses, the majority of which are non-functioning benign adrenal adenomas. In the presence of a known malignancy, such lesions have a more than 30% incidence of being metastases. As patients with gastrenteropancreatic neuroendocrine tumors (GEP-NETS) have mainly well-differentiated and slow-growing tumors and are subject to routine abdominal imaging for disease staging or during follow-up, it is important to study the incidence and significance of such lesions based on the recently introduced TNM classification system.

#745 Surgery after Peptide Receptor Radionuclide Therapy (PRRT) for Patients with Neuroendocrine Tumors (NETs) with Metastatic Abdominal Localizations.
Introduction: There are only few case reports about surgery in patients affected by gastroenteropancreatic neuroendocrine tumor (GEP-NET) patients previously underwent peptide receptor radionuclide therapy (PRRT).

#1675 Abdominal Obesity, Fasting Glucose and Metabolic Syndrome Are Risk Factors for Well Differentiated Digestive Neuroendocrine Tumors
Introduction: Digestive NETs(DNETs)`s incidence has increased last 40 years. Visceral obesity and metabolic syndrome (MetSyn) were recently reported to be associated with several cancers, although not so far with DNET.

#285 A Case of Primary Hepatic Carcinoid Tumor Misdiagnosed as Hepatocellular Carcinoma (HCC)
Introduction: Carcinoid tumors generally occur in the gastrointestinal and respiratory tracts. Primary carcinoid tumor of the liver is very rare. It may be misdiagnosed as hepatocellular carcinoma, which is very common.

#2059 Finding the Options of Good Prognosis for Ampullary Neuroendocrine Tumors
Introduction: Ampullary neuroendocrine tumors are very rare. They account less than 1% of neuroendocrine gastrointestinal tumor. It is often difficult to establish a final diagnosis because of their resemblance with other adenocarcinomas of this origin.
