Introduction And Importance:
Spinal meningiomas are typically intradural lesions. Some may infiltrate the dura mater, thus exhibit direct extradural extension. Pure spinal epidural meningiomas are very rare. Here we present a 64 year-old-male with a purely extradural meningioma, and reviewed 15 previously reported cases from the literature.
Case Presentation And Clinical Discussion:
A 64-year-old male presented with a progressive cauda equine syndrome. When Lumbar spine MRI showed two extradural lesions regarding the L3-L4 level, one was fully removed (i.e., the posterolateral lesion), while the other anterior lesion was left alone (i.e., to avoid potential neurologic sequelae). Pathologically, the lesion was a benign meningioma.
Conclusions:
Spinal epidural meningiomas are rare and should optimally be fully excised at the index surgery.
Insights
Purely extradural spinal meningiomas are exceptionally rare. This case highlights a benign meningioma in a 64-year-old male, emphasizing the need for complete surgical excision.
Area of Science:
- Neurosurgery
- Spinal Oncology
Background:
- Spinal meningiomas are typically intradural, but can extend extradurally.
- Purely spinal epidural meningiomas are exceedingly rare entities.
