Pituitary failure secondary to head trauma. Case report

Area of Science:

• Neuroendocrinology
• Traumatic Brain Injury

Background:

• Hypopituitarism can occur secondary to traumatic brain injury (TBI).
• Identifying pituitary deficits post-TBI is crucial for patient management.

Purpose of the Study:

• To report a case of hypopituitarism following severe head trauma.
• To illustrate the diagnostic findings and suggest management strategies.

Main Methods:

• Clinical presentation of a patient with hypopituitarism post-TBI.
• Hormonal assays including growth hormone, gonadotropins, and thyroid-stimulating hormone (TSH).
• Testing of TSH-releasing hormone (TRH) response and prolactin levels.

Main Results:

• Demonstrated deficits in growth hormone, follicle-stimulating hormone, and luteinizing hormone.
• Borderline TSH with normal TRH response and elevated prolactin.
• Indicated viable anterior pituitary tissue with impaired hypothalamic regulation.

Conclusions:

• Severe head trauma can lead to complex pituitary hormone deficiencies.
• The findings suggest inadequate hypothalamic control over pituitary function.
• Emphasizes the need for vigilance in recognizing and treating post-traumatic hypopituitarism.
