#255 The Carcinoid Syndrome Caused by Retroperitoneal Carcinoid Tumors
Introduction: The carcinoid syndrome is caused by increased levels of serotonin and is mostly seen in cases of carcinoid tumor in the small bowel and liver metastases, as there is a very high first pass effect.

#423 Case Report : A Rare Cause of Retroperitoneal Fibrosis Responding to Steroids
Introduction: Retroperitoneal fibrosis is a rare inflammatory disease. Neuroendocrine tumors are a heterogenous group that arise from enterochromaffin cells, most commonly in the gastrointestinal tract. Their capacity to secrete hormones, five HT, tachykinins etc, are responsible for symptoms known as carcinoid syndrome. However NETS, particularly arising from the midgut, can cause fibrosis. This can result in bowel obstruction, but also cause fibrosis in the retroperitoneum, lungs and cardiac valvular fibrosis.

#1729 Outstanding Response to Sunitinib in a Patient with Unresectable Retroperitoneal Paraganglioma
Introduction: Pheochromocitomas and Paragangliomas (PCs/PGLs) are rare neuroendocrine tumors arising from the adrenal medulla and extra-adrenal ganglia. Around 30-40% of these neoplasms are genetically determined. PCs/PGLs arising from the sympathetic chain can synthesize bioactive amines leading to typical syndromes, in contrast to parasympathetic PGLs that are mainly non-secretory.

#1006 The Use of Endoluminal Stents to Overcome Vascular Obstruction Arising from Mesenteric and Retroperitoneal Neuroendocrine Metastases
Introduction: Gastroenteropancreatic neuroendocrine tumors (GEP-NET) often metastasise to lymph nodes. Nodal metastases from neuroendocrine tumors in the distal small intestine commonly (>50%) develop in the mesentery and are often centred at the mesenteric root surrounding the major vessels supplying the bowel. Compression of these vessels, by the nodes or associated fibrosis, can lead to severe symptoms such as pain (secondary to bowel ischaemia ), ascites (from superior mesenteric vein obstruction) and bowel perforation. In view of the often indolent nature of GEP-NET, symptoms from lymph node masses can persist for years, causing significant morbidity and early mortality.

#317 Paraganglioma: Gallium-68 DOTOTATE PET CT Scanning, a Useful Addition to MIBG Scanning in Metastatic Disease
Introduction: Nuclear imaging forms an important part of the assessment of chromaffin cell tumors. MIBG scintigraphy has been available for some time, while 68Ga-DOTATATE PET CT is increasingly utilized.

#931 A Case of Adrenal Pheochromocytoma Rupture Treated with Transarterial Embolization (TAE)
Introduction: Spontaneous hemorrhage within a pheochromocytoma resulting in capsular rupture and hemorrhage is a rare condition, but also catastrophic and highly lethal event. An emergent operation for pehochromocytoma rupture is higher mortality than elective operation, and misdiagnosis and failure to control the hemorrhage lead directly to 100% mortality.

#2218 More than Rare Pheochromocytomas: Bilateral and Hemorrhagic, Giant and Metastatic
Introduction: Pheochromocytomas (PCC) are rare neuroendocrine tumors. These catecholamine-secreting tumors, with an average size of 4.9cm, are multiple in 10% of cases. About 10% are malignant but distant metastases are rare. Non-traumatic adrenal hemorrhage is an unusual potentially fatal event seen in PCC.

#2995 Prediction of Symptomatic Mesenteric Mass in Patients with Small Intestinal Neuroendocrine Tumors Using a CT Radiomics Approach
Introduction: A mesenteric mass surrounded by fibrosis is a hallmark feature of small intestinal neuroendocrine tumors (SI-NETs) that can induce severe abdominal complications. To improve clinical outcome, there is a need for personalized treatment strategies based on accurate prediction of development of abdominal complications.
