Traumatic arachnoid diverticula: a report of two cases causing spinal cord compression

Area of Science:

• Neurosurgery
• Traumatology
• Spinal Cord Injury

Background:

• Traumatic extradural diverticula are rare spinal pathologies.
• Motorcycle accidents are a significant cause of severe trauma.

Observation:

• Two cases of large traumatic extradural diverticula following motorcycle accidents are presented.
• These diverticula caused significant spinal cord compression.

Findings:

• One case involved a complication of total brachial plexus avulsion.
• The second case followed a closed spinal injury with probable brachial plexus traction and root sleeve rupture.

Implications:

• Highlights the potential for rare spinal complications from high-impact trauma.
• Emphasizes the importance of considering extradural diverticula in patients with neurological deficits after motorcycle accidents.
• Suggests a need for advanced imaging and surgical evaluation in such cases.
