Introduction: Acromegaly is a rare chronic disorder caused by growth hormone hypersecretion due to GH-producing pituitary adenoma. Surgery is the first-line treatment modality. However, patients with severe cardiac involvement are high-risk candidates for pituitary surgery. These patients may benefit from rapid preoperative biochemical control of acromegaly. There is emerging evidence of efficacy of pegvisomant, a GH-receptor antagonist, (either alone or in combination with so...

Background: Prolactinomas (PRL) are pituitary adenomas mainly characterized by hyperprolactinemia. In addition to the endocrine effects of prolactin, metabolic alterations have been described in PRL patients. Changes in inflammatory parameters have recently been identified in pituitary adenoma patients. Since both, metabolic (MM) and inflammatory markers (IM) showed promising results in characterization/prognosis of tumor patients, it is tempting to speculate whether those mig...

Introduction: The differential diagnosis of sellar masses is broad and includes - apart from the most common pituitary adenomas - other neoplasms such as craniopharyngiomas, germinomas, gliomas, meningiomas, and others. Hemangiopericytoma (HPC) is a rare vascular tumor arising from pericytes that may appear at any site of the body. We report an unusual case of an intrasellar HPC.Case Report: A 63-year-old woman was admitted to our hospital complaining ab...
