Cushing's syndrome is a collection of signs and symptoms due to prolonged exposure to glucocorticoids such as cortisol. [4] [9] [10] Signs and symptoms may include high blood pressure, abdominal obesity but with thin arms and legs, reddish stretch marks, a round red face due to facial plethora, [11] a fat lump between the shoulders, weak muscles, weak bones, acne, and fragile skin that heals ...
Results indicative of Cushing's disease involve no change in cortisol on low-dose dexamethasone, but inhibition of cortisol on high-dose dexamethasone. If the cortisol levels are unchanged by low- and high-dose dexamethasone, then other causes of Cushing's syndrome must be considered with further work-up necessary.
The symptoms of Cushing's disease are similar to those seen in other causes of Cushing's syndrome. [5] Patients with Cushing's disease usually present with one or more signs and symptoms secondary to the presence of excess cortisol or ACTH. [6] Although uncommon, some patients with Cushing's disease have large pituitary tumors (macroadenomas).
Cushing syndrome can be hard to diagnose. Here's what it is, as well as what causes it and how it's treated.
Inferior petrosal sinus sampling (or IPSS), is a diagnostic medical procedure used to determine whether excess adrenocorticotropic hormone (ACTH) is coming from the pituitary gland (usually a pituitary adenoma causing Cushing's disease) or from a source outside the pituitary (a rare tumor causing ectopic ACTH syndrome). The procedure is usually ...
Nelson's syndrome is a disorder that occurs in about one in four patients who have had both adrenal glands removed to treat Cushing's disease. [1] In patients with pre-existing adrenocorticotropic hormone ()-secreting pituitary adenomas, loss of adrenal feedback following bilateral adrenalectomy can trigger the rapid growth of the tumor, leading to visual symptoms (e.g. bitemporal hemianopsia ...
