PURPOSE OF THE STUDY: Orbital meningiomas are typically benign tumors, most commonly originating from the dura of the sphenoid wing or the optic nerve sheath.
PROCEDURES: We describe an unusual case of a malignant meningioma originating from the frontal lobe that ultimately produced orbital and distant metastases.
RESULTS AND CONCLUSIONS: Orbital invasion by the meningioma was preceded by multiple incomplete resections, which may have facilitated access to the orbit. The present case serves to remind clinicians that surgical resection of aggressive, recurrent frontal lobe meningiomas may facilitate subsequent penetration of surrounding structures, particularly by tumors that demonstrate bone-destructive properties.
