Diencephalic syndrome following cervical spinal cord trauma

Area of Science:

• Neurosurgery
• Endocrinology
• Trauma Medicine

Background:

• Cervical spine trauma can lead to complex neurological and endocrine complications.
• Diabetes insipidus (DI) is characterized by polyuria and polydipsia, often due to vasopressin dysfunction.
• The link between cervical spine injuries and DI is not well-established.

Purpose of the Study:

• To report and analyze cases of diabetes insipidus following traumatic cervical spine fractures or dislocations.
• To investigate the potential mechanisms underlying DI in the absence of direct cerebral trauma.

Main Methods:

• Case series analysis of five patients with traumatic cervical spine injuries.
• Clinical observation of polyuria and hyperthermia onset and resolution.
• Biochemical assessment including vasopressin urinary levels.
• CT scan examination for cerebral lesions.

Main Results:

• Five patients developed polyuria and hyperthermia days after cervical spine trauma.
• Symptoms regressed spontaneously or with vasopressin administration.
• Confirmed true diabetes insipidus through vasopressin urinary levels.
• No evident cerebral lesions were found on CT scans.

Conclusions:

• Traumatic cervical spine injuries may precipitate diabetes insipidus.
• The exact etiology remains unclear, but a central medullary pathway is hypothesized.
• Further research is needed to elucidate the pathophysiology of DI post-cervical trauma.
