About this study

Twenty to 40% of adrenal incidentalomas are responsible for MACS (mild autonomous cortisol producing secretion). The biological tools used in current practice to explore MACS do not provide precise information on cortisol production abnormalities. This study is a comparative analysis of the dynamics/rhythmicity of interstitial cortisol and other steroid concentrations between MACS and non-secreting adenomas (ANS). Using the original and innovative U-RHYTHM system, interstitial fluid samples will be taken every 20 minutes for 24 to 48 hours from patients with MACS or non-secreting adenomas, and steroid assays will be performed in the perfusates to analyze steroid hormone production over 24 hours.
