Summary
This study presents a rare case of ossified meningioma en plaque in the thoracic spine. Complete microsurgical removal was achieved, with expected good outcomes for this uncommon spinal tumor.
Area of Science:
- Neurosurgery
- Spinal Oncology
- Radiology
Background:
- Spinal meningiomas are tumors arising from the meninges of the spinal cord.
- Meningiomas en plaque are a subtype characterized by diffuse, flattened growth.
- Ossified meningiomas, particularly en plaque, represent a rare subset of these lesions.
Observation:
- A rare case of an ossified meningioma en plaque in the midthoracic spine is detailed.
- The tumor's unique characteristics were identified through specific neuroimaging findings.
- The lesion was completely removed via microsurgery.
Findings:
- Ossified meningiomas en plaque are exceptionally uncommon spinal neoplasms.
- Specific neuroimaging features can be pathognomonic for this rare tumor type.
- Complete resection is feasible and associated with favorable outcomes.
Implications:
- This case contributes to the understanding of rare spinal tumor presentations.
- Accurate neuroimaging is crucial for diagnosing ossified meningiomas en plaque.
- Successful microsurgical management offers a positive prognosis for patients.
