Insights
This study details the youngest reported case of a Sylvian fissure meningioma in a pediatric patient, highlighting its unique presentation and successful surgical removal. The findings contribute to understanding rare pediatric brain tumors.
Area of Science:
- Neurosurgery
- Pediatric Oncology
- Neuropathology
Background:
- Meningiomas are rare in children, with deep Sylvian fissure locations being exceptionally uncommon.
- Early diagnosis and surgical intervention are crucial for favorable outcomes in pediatric brain tumors.
Observation:
- A one-year-eight-month-old child presented with a convulsive seizure, later diagnosed with a large left temporal Sylvian fissure meningioma.
- Imaging revealed a well-enhanced tumor without dural attachment, supplied by the internal carotid artery.
- The tumor was strongly adhered to the M2 segment of the middle cerebral artery.
Findings:
- Complete surgical resection of the fibrous meningioma was achieved.
- Pathological examination confirmed a benign fibrous meningioma.
- This case represents the youngest reported instance of a pediatric deep Sylvian meningioma.
Implications:
- This case expands the understanding of pediatric Sylvian fissure meningiomas, particularly in very young children.
- Highlights the importance of advanced imaging and surgical techniques for managing complex pediatric brain tumors.
- Contributes to the literature on rare pediatric central nervous system neoplasms and their clinical characteristics.
Abstract:
We report a case of a Sylvian fissure meningioma in a one-year-eight-month old child who experienced the onset of a convulsive seizure. He had no neurological deficit and no developmental disorders. Computed tomography (CT) and magnetic resonance imaging (MRI) showed a large left temporal tumor which was well enhanced and without dural attachment. Angiography revealed a slight tumor stain in the left Sylvian fissure supplied by branches of the internal carotid artery. Total removal of the tumor was performed, and we found that the tumor had no dural attachment, but was strongly attached to the M2 segment of the left middle cerebral artery. Pathological examinations revealed it to be a fibrous meningioma without malignancy. This is the youngest case among the reported five pediatric deep Sylvian meningiomas. Introducing this case, we discuss the clinical features of pediatric meningiomas.
