Objective: Autonomous cortisol secretion (ACS) is the most common endocrine abnormality in the evaluation of adrenal incidentalomas. The categorization of ACS is derived from a 1 mg dexamethasone suppression test (DST). Impaired DST is associated with several metabolic derangements. In this study we assess the correlation between post-DST cortisol level, analyzed as a continuous parameter, and indices of glycemic metabolism.Study design: We prospectively...

Background: Borderline isolatednorepinephrine (NE) and normetanephrine (NMT) elevation is common among patients with suspected pheochromocytoma and paraganglioma (PPGL). The clonidine suppression test (CST) may help establish the etiology in these cases. Prolonged laboratory processing and/or paucity of reliable biochemical assaysmay limit the utility of CST. The aim of this study was to evaluate whether blood pressure (BP) reduction during CST is associated with alterations i...

ObjectiveAutonomous cortisol secretion (ACS) is the most common hypersecretion syndrome present in patients diagnosed with adrenal incidentalomas (AI). ACS is associated with various metabolic derangements. Thus far, very few and mostly inconclusive data exists regarding the association between AI’s radiological characteristics and hormonal functionality. In this study we assessed the associations between radiological characteristics of incidentally...
