Introduction: A substantial proportion of pheochromocytomas (PCC) are detected during the work-up of an adrenal incidentaloma. Recently it has been suggested that in case of an adrenal incidentaloma with an unenhanced attenuation value <10 Hounsfield Units (HU) on CT imaging biochemical testing to rule out PCC is unnecessary. We aimed to determine the sensitivity of the 10 HU cut-off value to detect pheochromocytoma.Methods: Retrospective multicenter...

Background/Aim: Neuroendocrine tumors (NETs) are rare tumors arising from neuroendocrine cells throughout the body. Positron Emission Tomography (PET) scanning with 6-[18F]fluor-L-3,4-dihydroxyphenylalanine (18F-FDOPA) has been shown to be a valuable technique for the imaging of NETs. While the sensitivity has been assessed numerously, studies systematically describing false positive results, other than physiological variants, are lacking. Our aim was to systematica...

Background: Administration of α-adrenergic receptor antagonists is recommended before resection of a pheochromocytoma (PCC) in order to prevent perioperative cardiovascular complications. For this purpose either phenoxybenzamine (PXB) or doxazosin (DOX) is commonly prescribed. We conducted the first randomized controlled trial comparing the efficacy of PXB and DOX in controlling perioperative hemodynamics in patients undergoing PCC resection (
