Head trauma can cause hypopituitarism, a condition affecting hormone production, which may be delayed for years. Early recognition and monitoring are crucial for managing neurobehavioral symptoms.

Area of Science:

  • Neuroendocrinology
  • Trauma Medicine
  • Endocrinology

Background:

  • Hypopituitarism following head trauma is often overlooked.
  • Neurobehavioral deficits associated with hypopituitarism can be improved with hormone replacement therapy.

Purpose of the Study:

  • To investigate the clinical presentations and imaging findings of hypopituitarism that develops after head trauma.
  • To highlight the importance of recognizing head trauma as a cause of hypopituitarism.

Main Methods:

  • Retrospective review of medical records of patients diagnosed with hypopituitarism between 1982 and 2002.
  • Analysis of disease history, hormone deficiencies, and imaging findings in patients with post-traumatic hypopituitarism.

Main Results:

  • Head trauma was the cause of hypopituitarism in 2.8% of patients, with road accidents being the most common cause.
  • Common hormone deficiencies included sex hormones (61%), growth hormone (56%), corticotropin (39%), and thyrotropin (22.2%).
  • Diabetes insipidus (DI) occurred in 50% of patients, with 5 having DI alone; pituitary MRI revealed small or atrophic anterior lobes and posterior lobe abnormalities in some cases.

Conclusions:

  • Delayed onset of hypopituitarism after head trauma can lead to missed diagnoses.
  • Diabetes insipidus is a frequent early complication, and anterior hypopituitarism can manifest years later.
  • Long-term monitoring for endocrine dysfunction is essential in patients with a history of head trauma.
