The Role of Magnetic Resonance Imaging and Endoscopic Ultrasound Imaging in the Diagnosis and Management of Pancreatic Neuroendocrine Tumors (pNET) in Patients with Multiple Endocrine Neoplasia Type 1 (MEN1)

#2285

Introduction: Pancreatic neuroendocrine tumors (pNETs) in patients with Multiple Endocrine Neoplasia Syndrome type 1 (MEN 1) are frequently multiple and occur with an incidence that varies from 30-80% in different series. Magnetic Resonance Imaging (MRI) and techniques such as endoscopic ultrasound (EUS) are useful tools for tumor localization, size assessment and follow-up.

Aim(s): The aim of the study was to compare imaging with MRI and EUS in pNET assesment in patients with MEN1.

Materials and methods: We collected retrospectively the data of 47 patients (mean age (±SD) at diagnosis 39±14 years, median: 39 years) with MEN1; 32 patients had pNETs. We analyzed and compared MRI and EUS findings ordered in the same follow-up visit and performed within the same trimester. We have analyzed the number and size of pancreatic lesions.
