Abstract:
Intracranial meningiomas in children are rare, representing 1-4.2% of central nervous system tumors and 1.5-1.8% of all intracranial meningiomas. Meningiomas arising from the lateral wall of the cavernous sinus account for less than 1% of all intracranial meningiomas. To our knowledge, only one case of a meningioma arising from the cavernous sinus has been reported in childhood. A 6-year-old boy presented with left ophthalmoplegia. A slight drooping of the left eyelid was noted at the age of 1 year. Magnetic resonance imaging (MRI) with contrast administration revealed an enhancing mass lesion located in the left cavernous sinus. The tumor, arising from the lateral wall of the cavernous sinus, was totally removed and the oculomotor nerve was reconstructed with a sural nerve graft. MRI displayed total tumor removal 1 month after the surgery. The pathological diagnosis was of a psammomatous meningioma.
Insights
Pediatric intracranial meningiomas are rare, especially those in the cavernous sinus. This report details a successful surgical removal and reconstruction for a 6-year-old boy with a psammomatous meningioma.
Area of Science:
- Pediatric neurosurgery
- Neuro-oncology
- Ophthalmology
Background:
- Intracranial meningiomas are uncommon in children, constituting a small fraction of central nervous system tumors.
- Meningiomas originating from the cavernous sinus lateral wall are exceedingly rare, representing less than 1% of all intracranial meningiomas.
Observation:
- A 6-year-old boy presented with progressive left ophthalmoplegia and ptosis, indicative of cranial nerve dysfunction.
- Magnetic resonance imaging (MRI) revealed an enhancing mass within the left cavernous sinus.
Findings:
- The patient underwent successful total surgical resection of the cavernous sinus meningioma.
- Oculomotor nerve function was reconstructed using a sural nerve graft, with imaging confirming complete tumor removal post-operatively.
- Pathological examination confirmed the diagnosis of psammomatous meningioma.
Implications:
- This case highlights the possibility of rare meningioma occurrences in pediatric cavernous sinus cases.
- Successful surgical management and nerve reconstruction can lead to favorable outcomes in pediatric cavernous sinus meningiomas.
- Further research into pediatric meningioma subtypes and treatment strategies is warranted.
