gastrinoma/headache

OBJECTIVE The objective of this case report is to demonstrate that the simple expedient of measuring periodic prolactin levels in patients with MEN1 who have modest hyperprolactinemia and normal pituitary MRI scans is insufficient to monitor for the development of pituitary adenomas. METHODS Review

Omeprazole, a substituted benzimidazole, has been shown to be a potent inhibitor of gastric acid secretion in patients with Zollinger-Ellison syndrome (ZES). We review our experience, as well as the published data on 210 patients with ZES who have required omeprazole for control of gastric acid

We report a case of synchronous bilateral pituitary adenomas in a patient with multiple endocrine neoplasia type one (MEN1). The patient was previously known to have a pancreatic gastrinoma and had first-degree relatives with MEN1. Both adenomas were concurrently revealed by high-resolution MR

MEN-1 is an autosomal dominantly inherited disorder, characterised by the occurrence of multiple tumours, particularly in the parathyroid glands, the pancreatic islets, the pituitary gland and the adrenal glands, as well as by neuroendocrine carcinoid tumours. Various clinical manifestations are
