Extradural Spinal Lymphoplasmacyte-Rich Meningioma in the Thoracic Spine: A Case Report and Literature Review
Journal of the Korean Society of Radiology
|October 14, 2022
Abstract:
Most spinal meningiomas have an intradural or partly extradural location. The meningothelial origin is the most common pathologic type of spinal meningioma. Pure extradural spinal meningiomas are not common, and lymphoplasmacyte-rich meningioma (LPRM) is very rare. We report a case of isolated extradural spinal meningioma in the thoracic spine that was pathologically confirmed as LPRM.
Insights
Pure extradural spinal meningiomas are rare, especially lymphoplasmacyte-rich meningioma (LPRM). This study details a unique case of isolated thoracic spine LPRM, highlighting its rarity and diagnostic confirmation.
Area of Science:
- Neurosurgery
- Pathology
- Oncology
Background:
- Spinal meningiomas typically occur intradurally or partly intradurally.
- Meningothelial origin is the most common subtype.
- Purely extradural spinal meningiomas are uncommon, with lymphoplasmacyte-rich meningioma (LPRM) being exceptionally rare.
