Introduction: Congenital adrenal hyperplasia (CAH) encompasses a group of enzymatic defects in cortisol biosynthesis resulting in adrenal hyperplasia through chronic compensatory ACTH stimulation. Aldosterone synthase deficiency, however, is associated with normal cortisol secretion and there are no reports on whether it may be associated with adrenocortical hyperplasia.Case Presentation: A 37-year-old, Greek female was referred for further investigation...

Background: In patients with adrenal nodules increased 17-OH Progesterone (17-OHP) does not necessarily indicate congenital adrenal hyperplasia (CAH) since adrenocortical tumors may harbor defects in steroidogenesis resulting in high steroid precursors, either basally or, usually, after Synacthen stimulation. Secretion of precursors has been associated with malignancy but it can also be present in benign adenomas.Case Presentation: A 62-year-old lady wit...

Background: ACTH-dependent Cushing’s syndrome (CS) is mostly associated with corticotroph adenomas or, infrequently, ectopic ACTH secretion(EAS). Adrenals may show diffuse bilateral enlargement or even macronodules. Adrenal metastases may occur in various cancers. They are often bilateral, irregular, with attenuation values >20 Hounsfield units(HU) on unenhanced CT scan and elevated SUVmax on FDG-PET scan. They may cause adrenal insufficiency due to the destruction of...
