#4563 Clinical case of a young woman with acromegaly, hyperprolactinemia and pituitary tumour with mixed morphology of adenoma and gangliocytoma

Introduction: Acromegaly is a rare disorder that develops due to persistent hypersecretion of somatotropic hormone in adults after closure of the growth plates. In the majority of cases, the cause is a pituitary adenoma.

#4382 Sensitivity of endoscopic ultrasound in detecting small gastrointestinal neuroendocrine tumours

Introduction: Small gastrointestinal neuroendocrine tumours (GI-NETs) are often difficult to detect using conventional imaging modalities, leading to delayed diagnosis and suboptimal treatment outcomes. Endoscopic ultrasound (EUS) has emerged as a promising tool for the early detection and precise localisation of these tumours. However, its sensitivity in identifying small lesions remains to be thoroughly evaluated.

#4203 The diagnostic role of DWI-MRI for liver metastases of neuroendocrine neoplasms (NENs) in comparison with the functional imaging

Introduction: A combination of morphological and functional imaging plays a crucial role for diagnosis, staging and therapeutic decision for neuroendocrine neoplasms (NENs). Diffusion-weighted imaging (DWI) magnetic resonance imaging (MRI) is emerging as a key imaging technique in the NEN field.

#3921 Mixed neuroendocrine-non-neuroendocrine neoplasms of the rectum: A case report

Introduction: Mixed Neuroendocrine-Non-Neuroendocrine Neoplasms (MiNEN) represent roughly 1-2% of all colorectal malignancies. Given the rareness and heterogeneity of these mixed tumors, recognition and accurate diagnosis remain a challenge. In the absence of established guidelines, they are treated according to the standard of care for pure neuroendocrine carcinomas or adenocarcinomas from similar sites of origin.
