Cause

Common Causes

Hypopituitarism and panhypopituitarism can be congenital or acquired. A partial list of causes and forms:

• Congenital hypopituitarism
  • Hypoplasia of the pituitary
    • Isolated idiopathic congenital hypopituitarism
    • Associated with other congenital syndromes and birth defects
      • Septo-optic dysplasia
      • Holoprosencephaly
      • Chromosome 22 deletion syndrome
      • Rapaport syndrome
  • Single gene defect forms of anterior pituitary hormone deficiency
• Acquired hypopituitarism (Simmonds' disease)
  • Trauma (e.g., skull base fracture)
  • Surgery (e.g., removal of pituitary neoplasm)
  • Tumor - secretory and non-secretory (20%) pituitary or hypothalamic neoplasms, cause hypopituitarism by compressing the remaining tissue
  • Inflammation (e.g. sarcoidosis or autoimmune hypophysitis)
  • Radiation (e.g., after cranial irradiation for childhood leukemia)
  • Shock
    • (Sheehan's syndrome is hypopituitarism after heavy bleeding in childbirth)
  • Hemochromatosis
• other diseases.
