Abstract:
Pediatric meningiomas are uncommon. Those presenting in the third ventricle are rare; there are only 15 cases reported in the literature. We report an additional third ventricular meningioma in a 6-year-old boy. The tumor was resected via an anterior transcallosal interfornicial approach. Postoperatively, the patient exhibited a transient episode of mutism. Unlike previous reports, the pathological diagnosis of this lesion was an atypical meningioma. The presentation, management, pathological features, and postoperative course of our case are discussed and compared with previous reports.
Insights
Pediatric meningiomas in the third ventricle are rare. This report details a case of atypical meningioma in a 6-year-old boy, highlighting its surgical resection and unique pathological findings.
Area of Science:
- Neuro-oncology
- Pediatric Neurosurgery
- Pathology
Background:
- Meningiomas are tumors arising from the meninges.
- Pediatric meningiomas are rare, with third ventricular location being exceptionally uncommon.
- Only 15 cases of third ventricular meningiomas in children have been previously documented.
Observation:
- A 6-year-old boy presented with a third ventricular meningioma.
- The tumor was surgically removed using an anterior transcallosal interfornicial approach.
- Post-surgery, the patient experienced a temporary period of mutism.
Findings:
- The pathological diagnosis revealed an atypical meningioma, differing from most prior reports.
- This case adds to the limited literature on pediatric third ventricular meningiomas.
- The surgical management and postoperative course were detailed and compared to existing literature.
Implications:
- This case expands the understanding of rare pediatric brain tumors.
- It underscores the importance of considering atypical histology in pediatric meningiomas.
- Findings may inform future surgical strategies and patient management for similar rare pediatric neoplasms.
