Case in brief
A 42-year-old woman presented with bilateral lower-extremity numbness due to a 41-mm ventral intradural extramedullary myxopapillary ependymoma located at T12-L1. The surgical approach involved contiguous T12-L1 recapping laminoplasty, allowing for en bloc tumor resection while preserving the capsule. Postoperatively, the patient experienced no neurological deterioration, and at 3 years, there was no evidence of tumor recurrence.
Diagnostic / clinical pearl
Contiguous T12-L1 recapping laminoplasty is an effective surgical technique for achieving en bloc resection of myxopapillary ependymomas at the thoracolumbar junction while maintaining posterior element integrity.
Why it matters
This case highlights the importance of innovative surgical techniques in managing complex spinal tumors, ensuring both effective tumor removal and preservation of neurological function.
