Traumatic hypopituitarism associated with bitemporal hemianopia in a prepuberal child

Area of Science:

• Neurology
• Endocrinology
• Ophthalmology

Background:

• Post-traumatic hypopituitarism is a rare endocrine disorder.
• Traumatic bitemporal hemianopia is a known visual field defect.
• Cranial trauma is an infrequent cause of hypopituitarism, often due to severe injuries.

Observation:

• A case study of a boy with post-traumatic hypopituitarism and bitemporal hemianopia is presented.
• The patient experienced visual field defects and hormonal deficiencies following head trauma.
• Diagnostic challenges in correlating clinical signs with specific lesions are noted.

Findings:

• Direct contusion necrosis or hemorrhage in the optic chiasm and pituitary/hypothalamus are probable causes.
• A transient compressive mechanism affecting the tubero-hypophysial arteries or infundibular vessels may explain concurrent injuries.
• The intricate vascular supply to the chiasm and anterior diencephalon is reviewed in relation to the syndrome's pathogenesis.

Implications:

• Understanding the pathogenesis of traumatic hypopituitarism is crucial for diagnosis and management.
• This case underscores the vulnerability of the pituitary and optic pathways to head injuries.
• Further research into the vascular mechanisms of traumatic brain injury-induced endocrine and visual deficits is warranted.
