Spinal extradural arachnoid cyst--case report

Area of Science:

• Neurosurgery
• Neurology
• Radiology

Background:

• Spinal arachnoid cysts are rare, benign lesions that can cause neurological deficits.
• Extradural arachnoid cysts in the thoracolumbar region are particularly uncommon.

Observation:

• A 48-year-old male experienced progressive leg weakness.
• Imaging studies revealed an extradural arachnoid cyst from T-12 to L-2.

Findings:

• Surgical exploration confirmed the presence of the extradural arachnoid cyst.
• Complete cyst excision was achieved during the surgical procedure.

Implications:

• Surgical removal of thoracolumbar extradural arachnoid cysts can lead to significant neurological recovery.
• This case highlights the importance of considering spinal arachnoid cysts in the differential diagnosis of progressive leg weakness.
