Concurrent intradural and extradural meningiomas of the cervical spine.

A case of an extradural spinal meningioma presenting with a separate intradural meningioma at the same cord level is reported. Review of the English literature on spinal epidural meningiomas reveals a high incidence of concurrent intradural tumors in patients with epidural meningiomas. This leads to the conclusion that the intradural space should be evaluated carefully when an epidural meningioma is encountered.
