A, B, and C: MRI with contrast showing multifocal meningioma seen along the left anterior clinoid process, left sphenoid wing, anterior temporal fossa, and planum sphenoidale with an invasion of the left pre-chiasmatic optic nerve and optic chiasm (arrow) compression (A: Axial sequence, B: CISS sequence, C: Coronal sequence).

D, E, and F: MRI after Tumor resection with residual lesion marked with a star (*) over the cavernous sinus and petroclival area. Both optic nerve-intracranial parts and optic chiasm (arrow) were freed. Temporal fossa pseudomningocele is seen in E (D: Axial sequence, E: Coronal sequence, F: Sagittal sequence).
