#4479 Bilateral adrenal masses associated with arterial hypertension with rare and unexpected definitive histopathological diagnosis: A case report

Introduction: During the clinical approach of bilateral adrenal masses, some imaging, biochemical and clinical guidelines are established to guide the diagnosis; however, only the histopathological result is what definitively establishes the diagnosis.

#4180 Non-functional alpha-cell hyperplasia with glucagonoma: A case report

Introduction: Alpha-cell hyperplasia(ACH) is a rare pancreatic endocrine condition. Clinically, 3 types have been described: functional ACH (nonglucagonoma hyperglucagonemic glucagonoma syndrome), reactive ACH (secondary to defective glucagon signalling) and non-functional ACH. Few cases of ACH and non-functional pancreatic neuroendocrine tumors (pNET) have been reported and its aetiology remains poorly understood.

#4121 The efficacy and safety analysis of transarterial embolisation in the treatment of cystic neuroendocrine neoplasm liver metastasis

Introduction: Liver metastases are common in neuroendocrine neoplasm (NEN). Cystic NEN liver metastases (cNENLM) are rare, and the efficacy of transarterial embolization (TAE) has not been reported.
