We routinely do laminotomy for such lesions if the tumour involves more than one vertebral height. If tumour is on one side hemilaminectomy is done. For one vertebral height tumours fenestration is done.
The reason to post this patient was that she had a noncontrast MRI cervical spine and it had been reported as intramedullary tumour, however I got a contrast MRI done which confirmed it to be intradural extramedullary well defined tumour. Note the enlargement of subarachnoid space at level just below tumour. Contrast is must in all tumour suspects.
