Optic Nerve Sheath Meningioma Masquerading as Optic Neuritis

Figure 1

Brain MRI T2 FLAIR axial (a, b) and sagittal (c) scans made at the time of presentation showing multiple nonenhancing hyperintense lesions in the periventricular, deep, and subcortical white matter. MR contrast-enhanced axial (d) and coronal (e, f) sequences of the orbit. The arrows pointed to a small extra-axial lesion with peripheral enhancement extending into the optic canal and apex of orbits surrounding the optic nerve with a small amount of fat stranding this region.
