[Left Sylvian fissure meningioma in a one-year-eight-month old child].
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.
