#2885 Ectopic Neuroendocrine Carcinoma: An Occult Source of ACTH

Introduction: About 250 cases of ectopic ACTH-producing neuroendocrine carcinoma (ACTH-NEC) have been reported; however metastatic ACTH-NEC of unknown primary is very rare. Usually are characterized by having a large cell, small cell, poorly differentiated or anaplastic cell, and Ki-67 index between 40-90%.

#2805 Small Bowel Neuroendocrine Tumor Metastases: Comparison of Contrast-Enhanced Computed Tomography and 68Ga-DOTATATE PET/CT

Introduction: Most gastrointestinal neuroendocrine tumors (GI-NETs) involve the small intestine (38%) and about 50% of patients present with regional or distant metastases at time of diagnosis [2]. 68Ga-DOTATATE PET/CT provides improved sensitivity and specificity compared to traditional nuclear medicine techniques [4]. However, there is relatively less data comparing performance of 68Ga-DOTATATE PET/CT with contrast-enhanced CT (CECT).

#2732 Prostate Metastasis of Medullary Thyroid Carcinoma in a Young Patient with MEN2B Syndrome

Introduction: Multiple Endocrine Neoplasia 2B is associated with particularly early onset medullary thyroid carcinoma (MTC). Metastatic MTC is the leading cause of early death in MEN2B. The usual sites of metastasis are neck, mediastinum, lung, liver, bone and brain.

#2185 Nonfunctional Pancreatic Neuroendocrine Tumor (NF PNET) Imaging and Evaluation Using 18F-FDG and 68Ga- DOTANOC-PET/CT: Initial Data of a Prospective Study

Introduction: Predicting aggressive behavior of NF PNET still remains controversial. It is known that lymph node metastases are rare but possible also on small (1-2 cm) NF-PNET. Positive 18F-FDG-PET/CT avidity is associated with poor prognosis in NETs.
