Abstract:
Ossified spinal meningiomas alone are uncommon lesions and spinal meningiomas en plaque are even more. A rare case is presented of ossified meningioma en plaque in the midthoracic spine, which was totally removed. Characteristics of this tumor with reference to relatively pathognomonic neuroimagings are discussed. Microsurgical outcome of this type of tumor is expected to be good.
Insights
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.
