S14.148 Brown-Sequard syndrome at C8 level of cervical spinal cord

Name of the Condition

• Brown-Sequard syndrome at C8 level of cervical spinal cord

Summary

This condition is a specific type of spinal cord injury characterized by a hemisection (partial damage to one side) of the cervical spinal cord at the C8 level. It results in a distinct pattern of neurological deficits, including ipsilateral (same side) motor weakness or paralysis and loss of proprioception (position sense) below the injury level, combined with contralateral (opposite side) loss of pain and temperature sensation. The C8 level is part of the cervical spinal cord, which transmits signals between the brain and the upper body, so injuries here can affect motor, sensory, or autonomic functions.

Causes

Brown-Sequard syndrome at the C8 level is typically caused by traumatic events, such as penetrating injuries (e.g., stab wounds or gunshot wounds) that damage one side of the spinal cord. Other traumatic causes include fractures, dislocations, or severe compression of the cervical spine. Non-traumatic causes, such as tumors, infections, or inflammatory conditions (e.g., multiple sclerosis), may also lead to this syndrome by affecting one side of the spinal cord.

Risk Factors

• Participation in high-impact sports or activities with a risk of neck injury.
• Occupations involving heavy lifting or repetitive neck strain.
• Conditions that weaken bone or tissue.

Symptoms

Symptoms include ipsilateral motor weakness or paralysis, loss of proprioception, and contralateral loss of pain and temperature sensation below the injury level. Autonomic dysfunction may also occur.

Diagnosis

Diagnosis involves clinical evaluation of neurological deficits, imaging (e.g., MRI) to identify spinal cord damage, and exclusion of other conditions with similar presentations.

Treatment Options

Treatment focuses on stabilizing the spine, managing symptoms, and rehabilitation. Interventions may include surgery, physical therapy, and medications to address pain or spasticity.

Prognosis and Follow-Up

Prognosis depends on injury severity and timely intervention. Follow-up includes monitoring for recovery, managing complications, and adjusting rehabilitation plans as needed.

Complications

Potential complications include chronic pain, spasticity, autonomic dysfunction, and long-term mobility or sensory impairments.

Lifestyle & Prevention

Preventive measures include using protective gear during high-risk activities, maintaining spinal health, and avoiding behaviors that increase neck injury risk.

When to Seek Professional Help

Seek immediate medical attention for neck trauma, sudden neurological symptoms, or worsening motor/sensory deficits.

Tips for Medical Coders

Document the specific cervical level (C8) and confirm hemisection of the spinal cord. Ensure clinical notes support the diagnosis and differentiate from other spinal cord injuries.
