Post-trauma hypopituitarism, a rare condition, can manifest years after head injury. This case highlights isolated corticotrope insufficiency following cranio-facial trauma.

Area of Science:

  • Endocrinology
  • Neuroscience

Background:

  • Post-trauma hypopituitarism is a rare endocrine disorder, comprising only 3% of hypopituitarism cases.
  • High-energy head trauma is the most common cause of post-traumatic hypopituitarism.

Observation:

  • A 56-year-old woman presented with central diabetes insipidus post-cranio-facial trauma.
  • Four years later, she developed asthenia and hypoglycemia, indicating isolated corticotrope insufficiency.
  • MRI revealed an intrasellar arachnoidocele and absent posterior pituitary gland hypersignal.

Findings:

  • Hypopituitarism exceptionally involves a single hormone deficiency, with growth hormone deficiency being common.
  • Pathogenesis often involves hypothalamic dysfunction rather than direct pituitary gland failure.

Implications:

  • This case underscores the potential for delayed-onset, single-hormone deficiencies after head trauma.
  • Understanding the hypothalamic-pituitary axis is crucial for diagnosing and managing post-traumatic endocrine dysfunction.
