Sheehan syndrome

Sheehan syndrome is a rare cause of pituitary apoplexy and hypopituitarism.

It only occurs in postpartum females who experience large volume haemorrhage and hypovolaemic shock, either during delivery or afterwards.

  • pituitary failure 1
    • may be silent and present with delayed hypopituitarism
    • agalactorrhoea
    • amenorrhoea
    • oligomenorrhoea
    • adrenal insufficiency
    • hyponatraemia (diabetes insipidus) in the acute setting of extreme hypovolaemia
    • hypothyroidism
    • growth hormone deficiency
  • optic chiasm compression
    • visual field loss
    • headache
    • ophthalmoplegia

Hypovolaemia secondary to postpartum haemorrhage leads to pituitary infarction and necrosis.
