Introduction: Parathyroid adenoma is the most common cause of primary hyperparathyroidism (PHPT) resulting in hypercalcemia and hypercalciuria due to autonomous secretion of PTH. Ectopic parathyroid adenoma, as a consequence of variability in the glandular tissue migration during the embryologic life or a supernumary fifth parathyroid gland, has an incidence of 25% among patients with PHPT. The incidence of deeply mediastinal ectopic parathyroid adenoma is 1–3%.<p cla...

Introduction: Gonadotrophin-producing pituitary adenomas are usually non-functioning masses, and are not associated with elevated serum gonadotrophins. Functioning LH-producing gonadotroph pituitary adenomas are exceedingly rare in males, causing elevation of serum testosterone.Case report: We present an adult male who has been admitted to the emergency department a comatose state. Brain MRI revealed a large, lobulated mass of 6 cm caudal and 7.8 cm late...

Background: The prevalence of incidentally discovered adrenal masses has increased during last decades, due to longer life expectancy and to the extended use of new imaging techniques like high definition C/T and MRI. Diagnostic approach and possible therapeutic management are considered nowadays fascinating challenges for clinical practice, not only for the probability of hormonal hypersecretion but also for the risc of malignancy.Methods: We investigat...
