Rarely a cat may have double adenomas. In a few cases the diagnosis has been pituitary acidophilic hyperplasia. In dogs nearly all cases of acromegaly are caused by endogenous or exogenous progestogens, this causes a hypersecretion of growth hormones from the mammary gland. Pituitary tumours causing excess growth hormone secretion are very rare ...
The symptoms of Cushing's in cats is similar to that of dogs. [8] For cats the most common reason for referral resulting in a diagnosis is diabetes mellitus. Abnormal dermatological findings were the most common reason for referral after physical examination in cats. [9] 80% of cats with Cushing's develop diabetes mellitus compared to 10% of ...
MRI showed the cat to have a small pituitary gland with the sella turcica being near empty. [2] Common symptoms are lethargy, anorexia, obesity, and dermatological conditions such as alopecia. In addition the torpidity of the cat will cause a decrease in grooming which may lead to matting and poor coat condition. [2]
Secondary adrenocortical insufficiency involves only a deficiency of glucocorticoid secretion. Destructive lesions (e.g. neoplasia, inflammation) in the pituitary gland or hypothalamus and chronic administration of exogenous glucocorticoids or megestrol acetate (cats) are the most common causes.

The diaphragma sellae or sellar diaphragm is a small, circular sheet of dura mater forming an (incomplete) roof over the sella turcica and covering the pituitary gland lodged therein. The diaphragma sellae forms a central opening to accommodate the passage of the pituitary stalk (infundibulum) [ 1 ] which interconnects the pituitary gland and ...
It is a rare disease in dogs, with cats seven to ten times more likely to be infected. The disease in dogs can affect the lungs and skin, but more commonly the eye and central nervous system. [20] Ringworm is a fungal skin disease that in dogs is caused by Microsporum canis (70%), Microsporum gypseum (20%), and Trichophyton mentagrophytes (10% ...
The pituitary gland or hypophysis is an endocrine gland in vertebrates. In humans , the pituitary gland is located at the base of the brain , protruding off the bottom of the hypothalamus . The human pituitary gland is oval shaped , about 1 cm in diameter, 0.5–1 gram (0.018–0.035 oz) in weight on average, and about the size of a kidney bean .
Herring bodies or neurosecretory bodies are structures found in the posterior pituitary. They represent the terminal end of the axons from the hypothalamus, and hormones are temporarily stored in these locations. They are neurosecretory terminals. [1]
