OBJECTIVE AND IMPORTANCE: A case of chordoid meningioma originating in the right sylvian fissure is reported. Chordoid meningiomas are uncommon tumors. This is the first reported case of a chordoid meningioma without dural attachment arising in the sylvian fissure. CLINICAL PRESENTATION: The patient presented with a generalized seizure. A heterogeneously enhancing right frontotemporal mass was identified on magnetic resonance imaging of the brain. INTERVENTION: The patient underwent a failed stereotactic biopsy attempt elsewhere. The tumor was ultimately resected using standard microsurgical techniques. CONCLUSION: Meningiomas originate from arachnoid cap cells and can arise at locations remote from the pachymeninges. Although rare, meningiomas should be included on the differential diagnosis of sylvian fissure lesions.
