  2. Nelson's syndrome - Wikipedia

    en.wikipedia.org/wiki/Nelson's_syndrome

    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 ...

  3. Cushing's syndrome (veterinary) - Wikipedia

    en.wikipedia.org/wiki/Cushing's_syndrome...

    Cutaneous atrophy in a dog with Cushing's. Cushing's syndrome is classified as either pituitary-dependent, adrenal-dependent, or iatrogenic. [2] Pituitary-dependent Cushing's is caused by an adrenocorticotropic hormone producing pituitary tumour. Adrenal-dependent Cushing's is caused by an adrenal tumour. [4]

    A CT or MRI of the pituitary may also show the ACTH-secreting tumor if present. However, in 40% of Cushing's disease patients MRI is unable to detect a tumor. [8] In one study of 261 patients with confirmed pituitary Cushing's disease, only 48% of pituitary lesions were identified using MRI prior to surgery.

  5. Sudden acquired retinal degeneration syndrome - Wikipedia

    Despite similar symptoms and blood test results to Cushing's disease, evaluation of dogs with SARDS did not reveal any tumors in the pituitary or adrenal glands, [9] and recent work has indicated significant differences in the clinical and laboratory test parameters between the two diseases. [10]

  6. Cushing's syndrome - Wikipedia

    en.wikipedia.org/wiki/Cushing's_syndrome

    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 ...

  7. Canine brain tumors - Wikipedia

    en.wikipedia.org/wiki/Canine_Brain_Tumors

    Pituitary gland tumors are very common in the canine. A productive form arising from the anterior pituitary is the primary cause of Cushing's disease of dogs. This tumor causes excessive production of cortisol from the adrenal cortex which leads to the classic signs of alopecia (hair loss), polyuria (excessive urination), polydipsia (excessive water drinking), and a pot-bellied appearance of ...

  8. Hypoadrenocorticism in dogs - Wikipedia

    en.wikipedia.org/wiki/Hypoadrenocorticism_in_dogs

    Hypoadrenocorticism in dogs, or, as it is known in people, Addison's disease, is an endocrine system disorder that occurs when the adrenal glands fail to produce enough hormones for normal function. The adrenal glands secrete glucocorticoids such as cortisol [ 1 ] and mineralocorticoids such as aldosterone ; [ 2 ] when proper amounts of these ...

  9. Empty sella syndrome - Wikipedia

    en.wikipedia.org/wiki/Empty_sella_syndrome

    Secondary empty sella syndrome is the result of the pituitary gland regressing within the cavity after an injury, surgery, or radiation therapy. [3] Individuals with secondary empty sella syndrome due to destruction of the pituitary gland have symptoms that reflect the loss of pituitary functions, such as intolerance to stress and infection.
