Summary
This study reports the first intraspinal bronchiogenic cyst in the thoracolumbar spine. Surgical removal of this rare intradural extramedullary mass can lead to positive patient outcomes.
Area of Science:
- Neurosurgery
- Pathology
- Spinal Imaging
Background:
- Intradural extramedullary bronchiogenic cysts are exceptionally rare spinal tumors.
- Previous cases have been exclusively documented in the cervical and upper thoracic regions.
Observation:
- A 41-year-old patient with spina bifida occulta presented with intractable left leg pain.
- MRI revealed an intradural extramedullary mass at the T12-L1 level.
- The mass was partially resected after T-12 to L-1/L-2 laminectomy, revealing attachment to the conus medullaris and cauda equina.
Findings:
- Histopathological analysis confirmed the diagnosis of a bronchiogenic cyst.
- This case represents the first documented instance of such a cyst in the thoracolumbar spine.
Implications:
- Intradural extramedullary bronchiogenic cysts can occur in the thoracolumbar spinal region.
- Despite challenges in complete resection due to anatomical attachments, surgical intervention can yield favorable outcomes.
