A Symptomatic Spinal Extradural Arachnoid Cyst with Lumbar Disc Herniation
Spinal epidural arachnoid cyst (EAC) is a rare, usually asymptomatic condition of unknown origin, which typically involves the lower thoracic spine. We report a case of posttraumatic symptomatic EAC with lumbar disc herniation. A 22-year-old man experienced back pain and sciatica after a traffic accident.

A 48-year-old male presented with progressive leg weakness. Magnetic resonance imaging and computed tomography myelography showed an extradural arachnoid cyst extending from the T-12 to L-2 levels in the thoracolumbar region. The cyst was confirmed at surgery and completely removed. This surgical intervention achieved improvement in the neurological symptoms.

A spinal extradural arachnoid cyst (SEAC), which is mostly found at the thoracic spine, is a rare disease, accounting for approximately 1% to 3% of spinal tumors. SEAC patients are generally men in their 20’s, 30’s, or 50’s. SEACs are most commonly found in the middle or lower thoracic spine, and less frequently found in the lumbar region, although they can be detected at any lesion of the spin...

متن کاملSymptomatic Large Spinal Extradural Arachnoid Cyst: A Case Report
Spinal extradural arachnoid cysts (SEACs) are relatively rare cause of compressive myelopathy. SEACs can be either congenital or acquired, but the etiology and the mechanism for their development are still unclear. A number of cases have been reported in the literature, and the one-way valve mechanism is the most widely accepted theory which explains the expansion of cysts and spinal cord compr...
