Spinal meninigioma

Abstract

Spinal meningiomas represent almost one third of all intradural extramedullary tumors and occur rarely in men. They arise from arachnoid cap cells in the arachnoid cell rests within the meninges and can compress and displace the spinal cord and the nerve roots leading to motor and sensory impairment and also sphincter dysfunction. Most of them are benign with very good outcome after complete surgical resection. Imaging can be challenging in differentiating them from nerve sheath tumors including spinal schwannoma and spinal neurofibroma.
