Summary
A rare clear cell meningioma was found in the cauda equina of a 34-year-old patient. This spinal tumor, typically seen in younger individuals, was successfully removed without dural attachment, showing no recurrence.
Area of Science:
- Neurosurgery
- Spinal Oncology
- Neuropathology
Background:
- Clear cell meningioma is a rare subtype of meningioma, recently classified by the World Health Organization.
- This specific subtype typically affects younger patients and has distinct histological features.
- Spinal meningiomas, while uncommon, can present with neurological deficits requiring surgical intervention.
Observation:
- A 34-year-old female presented with chronic leg, hip pain, and voiding difficulties.
- MRI revealed a well-demarcated intradural extramedullary mass at L2-3, hypo-intense on T1/T2 sequences with homogeneous enhancement.
- The tumor demonstrated a lack of dural adhesion, facilitating complete surgical resection.
Findings:
- Histological examination confirmed the mass as a clear cell meningioma.
- The patient underwent successful surgical removal of the cauda equina tumor.
- Postoperative follow-up for two years showed no evidence of tumor recurrence.
Implications:
- This case highlights the possibility of clear cell meningioma occurring in an adult patient presenting with spinal symptoms.
- The absence of dural attachment in this case contributed to a favorable surgical outcome.
- Reporting rare spinal meningioma presentations aids in refining diagnostic and treatment strategies for these uncommon tumors.
