Hypoglycaemia in a Patient with Glucagonoma-Coincidence of a Glucagonoma and Insulinoma in a Patient with Multiple Endocrine Neoplasia Type I Abstract #1063

Introduction: We report the case of a 54 year old female with a known MEN1 syndrome with primary Hyperparathyroidism, a Prolactinoma and a pancreatic tumor. The patient complains about episodes of fatigue and sweating, both symptoms improve immediately after a meal.
Aim(s): Lab tests show a fasting glucose of 45 mg/dl, (without hypoglycaemic symptoms). A MRI of the pancreas shows a tumor with typical radiologic characteristics of a pancreatic neuroendocrine Tumor (PNET) with an increasing diameter from 22 to 27 mm (compared to one year ago). Further lab tests show an elevated glucagon level with 942 pg/ml (- 250 pg/ml). Insulin and C-peptide values were in the lower normal range.
Materials and methods: Due to the clinical symptoms and the increase in tumor size a left sided pancreatectomy and splenectomy was performed.

#1438 An Unusual Phenotype of Multiple Endocrine Neoplasia Type 1 with a Small Intestine Neuroendocrine Tumor Associated with Large Deletion of the MEN1 Gene
Introduction: Multiple endocrine neoplasia type 1 (MEN1) is an autosomal dominant inherited tumor syndrome that is caused by germline mutations in the Menin suppressor gene on chromosome 11q13. Small intestine neuroendocrine neoplasias (SI-NEN) are currently not considered to be part of the phenotype of the MEN1-syndrome.
