Discussion
Spinal meningiomas are mostly intradural in location although at times these are associated with some extradural extensions.
Common intradural extramedullary tumors are schwannomas, neurofibromas, and meningiomas while metastases form the bulk of the extradural lesions.
Typically on MRI, the lesion looks iso- or hypointense on T2-weighted images, in contrast to most hyperintense epidural tumors, barring lymphomas, which can be hypointense in up to 50% of the cases
