Extradural Spinal Meningioma: Mimicking Metastasis

Meningiomas are usually arise within the dura, sometimes extend beyond it, but completely outside the dura are very rare. Spinal meningiomas represent around 10% of all meningiomas and, commonly occur as intradural extramedullary lesions. Purely extradural spinal meningiomas are very rare and only few cases are reported in literature. We describe a case of 50yr old female who presented with upper dorsal region pain and sensory-motor spastic paraparesis. Imaging features were suggestive of D1-3 epidural lesion with significant cord compression. Patient underwent complete excision of lesion. On HPE, a diagnosis of meningothelial meningioma was made. Post-operatively patient showed a good clinical outcome without any recurrence during follow-up of 6 months.
