Summary
This study reports the first case of an aggressive intramedullary clear cell meningioma (CCM) in the thoracic spinal cord. This rare tumor variant presents unique diagnostic and treatment challenges.
Area of Science:
- Neurosurgery
- Oncology
- Spinal Cord Pathology
Background:
- Clear cell meningioma (CCM) is a rare and aggressive subtype of meningioma.
- Intramedullary meningiomas are exceptionally uncommon, with only one previous spinal case documented.
- The thoracic spinal cord is a rare location for meningioma development.
Observation:
- A patient presented with symptoms indicative of a spinal cord lesion.
- Diagnostic imaging revealed a tumor within the thoracic spinal cord.
- Histopathological examination confirmed the presence of an intramedullary clear cell meningioma.
Findings:
- This case represents the first documented instance of an intramedullary CCM in the thoracic spinal cord.
- The tumor exhibited aggressive histological features characteristic of CCM.
- The successful surgical resection and subsequent management are detailed.
Implications:
- This case expands the known spectrum of meningioma presentation and location.
- Understanding the behavior of intramedullary CCM is crucial for effective patient management.
- Further research into the pathogenesis and treatment of this rare entity is warranted.
