Disorders of the pituitary gland and its hypothalamic control

Acromegaly and gigantism

Other and unspecified anterior pituitary hyperfunction

Panhypopituitarism
- diminution or cessation of secretion of one or more hormones from the anterior pituitary gland (including luteinizing hormone, follicle stimulating hormone, somatotropin; and corticotropin); may result from surgical or radiation ablation, non-secretory pituitary neoplasms, metastatic tumors, infarction, pituitary apoplexy, infiltrative or granulomatous processes, and other conditions.
- A condition of diminution or cessation of secretion of one or more hormones from the anterior pituitary gland. This may result from surgical or radiation ablation, non-secretory pituitary neoplasms, metastatic tumors, infarction, pituitary apoplexy, infiltrative or granulomatous processes, and other conditions.

Pituitary dwarfism
- form of dwarfism due to deficient release of growth hormone which may result from dysfunction of the hypothalamus or anterior pituitary gland.

Other anterior pituitary disorders

Diabetes insipidus
- metabolic disorder due to injury of the neurohypophyseal system; results in deficient quanity of antidiuretic hormone being released or produced, failure of tubular reabsorption of water in the kidney.

Other disorders of neurohypophysis
- A syndrome characterized by abnormal secretion of antidiuretic hormone in conjunction with neoplastic growth occurring anywhere in the body.

Iatrogenic pituitary disorders

Other disorders of the pituitary and other syndromes of diencephalohypophyseal origin
- Rathke's pouch cysts are rarely symptomatic in the first two decades of life though they may produce symptoms in the third and fourth decades of life. When the cysts do present in the first decades of life, the symptoms are generally associated with diabetes insipidus or other conditions related to hypopituitarism.

Unspecified disorder of the pituitary gland and its hypothalamic control
- disorders of the anterior or posterior pituitary gland which usually manifest as hypersecretion or hyposecretion of pituitary hormones.
