Münchhausen's syndrome (MS) is a chronic factitious disorder characterized by the intentional production of clinical symptoms without external incentive. One type of MS is factitious Cushing syndrome, an extremely rare clinical situation in which the diagnosis is challenging mainly due to interference of the exogenous medication in cortisol immunoassays. We described a 26-year-old woman who was...

Simultaneous bilateral inferior petrosal sinus sampling (BIPSS) plays a crucial role in the diagnostic work-up of Cushing's syndrome. It is the most accurate procedure in the differential diagnosis of hypercortisolism of pituitary or ectopic origin, as compared with clinical, biochemical and imaging analyses, with a sensitivity and specificity of 88-100% and 67-100%, respectively. In the settin...

CONTEXT Cushing Syndrome is difficult to diagnose, and the comorbidities and persistent late effects of hypercortisolemia after treatment of the primary disease are challenging for the patient and the endocrinologist. OBJECTIVE To report the case of a girl with obesity and hypertension, ultimately diagnosed with Cushing syndrome due to primary pigmented nodular adrenocortical disease. In this...

Recent studies from several groups have indicated that abnormal or ectopic expression and function of adrenal receptors for various hormones may regulate cortisol production in ACTH-independent hypercortisolism. Gastric inhibitory polypeptide (GIP)-dependent Cushing's syndrome has been described in patients with either unilateral adenoma or bilateral macronodular adrenal hyperplasia; this syndr...

Structural and functional impairment of the skeletal system remains an important cause of morbidity and disability in patients with Cushing's syndrome (CS). Glucocorticoid (GC) excess inhibits bone formation and calcium absorption from the gut, increases bone resorption, and alters the secretion of gonadotropin and growth hormones, cytokines and growth factors influencing bone. Both overt and s...

In a previous study from our group [A. Khiat, C. Bard, A. Lacroix, J. Rousseau, Y. Boulanger, Brain metabolic alterations in Cushing's syndrome as monitored by proton magnetic resonance spectroscopy, NMR Biomed. 12 (1999) 357-363], proton magnetic resonance spectroscopy (1H MRS) was used to evaluate changes in cerebral metabolites in patients with Cushing's syndrome as compared to normal subjec...

BACKGROUND Cushing's syndrome is the term used to describe a set of symptoms associated with hypercortisolism, which in most cases is caused by hypophysial microadenoma over-secreting adrenocorticotropic hormone. This endocrine disorder is often associated with psychiatric comorbidities. The most important include mood disorders, psychotic disorders, cognitive dysfunctions and anxiety disorders...
