==Overview==
==Overview==
Hypopituitarism causes can be classified based upon the etiology such as [[congenital]] or [[acquired]]. Congenital causes include [[idiopathic]], [[anatomic]] [[lesion]] in the [[sella turcica]], and [[CNS]] [[malformations]]. Common causes among acquired causes include [[pituitary macroadenoma]], [[craniopharyngioma]], [[surgery]], [[radiation]], [[traumatic brain injury]], [[Sheehan's syndrome]], [[apoplexy]], [[Subarachnoid hemorrhage|SAH]], [[meningitis]], [[hypophysitis]], [[meningioma]], [[lymphoma]], [[hemochromatosis]] and Wegner's [[granulomatosis]]. Less common causes include Peri-natal insults, [[genetic]] causes, such as [[Kallman syndrome]], [[Pallister-Hall syndrome]], Rieger syndrome, and [[Pituitary gland|pituitary]] [[hypoplasia]] or [[aplasia]]. Hypopituitarism can also be classified based upon the anatomical location of the pathology such as [[hypothalamus]] or [[pituitary gland]].
Causes of hypopituitarism  can be classified based upon the etiology into [[congenital]] or [[acquired]]. Common [[congenital]] causes include [[idiopathic]], [[anatomic]] [[lesion]] in the [[sella turcica]] and [[CNS]] [[malformations]]. Common [[acquired]] causes may include [[pituitary macroadenoma]], [[craniopharyngioma]], [[surgery]], [[radiation]], [[traumatic brain injury]], [[Sheehan's syndrome]], [[apoplexy]], [[Subarachnoid hemorrhage|SAH]], [[meningitis]], [[hypophysitis]], [[meningioma]], [[lymphoma]], [[hemochromatosis]] and [[Wegener's granulomatosis|Wegner's granulomatosis]]. Less common causes include Peri-natal insults, [[genetic]] causes, such as [[Kallman syndrome]], [[Pallister-Hall syndrome]], Rieger syndrome, and [[Pituitary gland|pituitary]] [[hypoplasia]] or [[aplasia]].


==Common Causes==
==Common Causes==
Causes can be classified based upon the etiology such as [[congenital]] or [[acquired]]. The most common cause is pituitary tumor. Other possible causes may include cyst or a tumor in hypothalamus or infundibulum, vascular disorders, infiltrative diseases, genetic disorders, radiation, and surgery.

Overview

Causes of hypopituitarism can be classified based upon the etiology into congenital or acquired. Common congenital causes include idiopathic, anatomic lesion in the sella turcica and CNS malformations. Common acquired causes may include pituitary macroadenoma, craniopharyngioma, surgery, radiation, traumatic brain injury, Sheehan's syndrome, apoplexy, SAH, meningitis, hypophysitis, meningioma, lymphoma, hemochromatosis and Wegner's granulomatosis. Less common causes include Peri-natal insults, genetic causes, such as Kallman syndrome, Pallister-Hall syndrome, Rieger syndrome, and pituitary hypoplasia or aplasia.

Common Causes

Causes can be classified based upon the etiology into congenital or acquired. The most common cause is a pituitary tumor. Other possible causes may include cyst or a tumor in hypothalamus or infundibulum, vascular disorders, infiltrative diseases, genetic disorders, radiation, and surgery.

Etiology Underlying cause/disease
Congeital Idiopathic
Anatomic lesion in sella turcica: Rathke's cyst
CNS malformations: septo-optic-dysplasia, Kallmann syndrome, and pituitary stalk interruption syndrome
Acquired Pituitary tumor: mainly displacing macroadenoma (non-functioning or functioning adenomas)
Posterior pituitary tumor: astrocytoma, ganglioneuroma
Metastatic: breast, lungs, colon, prostate
Peripituitary lesions: Craniopharyngioma, meningioma, chordoma, optic nerve glioma
Surgery: Transsphenoidal or transcranial surgery in the hypothalamo-pituitary region
Radiation
Systemic cancer treatment
Traumatic brain injury
Sheehan's syndrome
Pituitary apoplexy
Meningitis
Hypophysitis
Lymphoma

Risk calculators and risk factors for Hypopituitarism causes

Etiology based on anatomical location of pathology:

Hypopituitarism can be classified based upon the anatomical location of pathology such as hypothalamus or pituitary gland.[15][16][17][18][19][20][21][22][3][10][23][9][12][24][25][26][27][8][28][29][30][31][32][33][34][35][36][37][38][39][40][41][42][43]

Anatomical location Cause
Hypothalmic Mass lesions: 
Radiation : CNS and nasopharyngeal malignancies
Infections: Tuberculous meningitis
Infiltrative lesions:
Other :
Pituitary Mass lesions:
Pituitary radiation
Pituitary surgery
Infection or abscess
Infiltrative lesions:

1. Hypophysitis:

2. Hemochromatosis

Infarction: Sheehan's syndrome
Apoplexy
Empty sella 
Genetic mutations

Genetic Causes

Hypopituitarism is caused by mutation in any one of the following genes.[44][45][46][47][48][49][50][51][52][53][54][55][56][57][58][59][60][61][62][63]
