Removal of Intradural Extramedullary Schwannoma at Lumbar Level by Doing Laminoplasty in Paediatric Patient- A Case Report and Review of Literature

Abstract

Intradural Extramedullary tumour of thoracolumbar spine has been mainly treated with laminectomy till date. Other approach has been of treating this pathology by doing laminoplasty. Objective of this case presentation is that laminoplasty is better option for IDEM in selected cases. Laminectomy has been associated with many complications which can be avoided by doing laminoplasty such as postoperative spinal instability, epidural fibro¬sis, kyphotic deformity, excessive blood loss, hematoma invasion, progressive myelopathy, persistent back pain and prolonged hospital stay. So laminoplasty has clearly advantage compared to laminectomy in preserving posterior arch of the spine. Revision surgery is also easier when primary surgery has been done by laminoplasty. In our case of 13-year-old boy having Intradural Extramedullary Schwannoma at L3 level, he was treated with flipping laminoplasty and tumour excision. At final follow up he was having complete clinical recovery and fully healed laminoplasty assessed with CT scan without any recurrence of tumour or any spinal deformity. It proves our purpose of doing laminoplasty with better outcome compared to laminectomy. Keywords: Laminoplasty; Laminectomy; Intradural Extramedullary; Spinal Cord Tumour.
