Optic Nerve Meningioma Vs Optic Nerve Glioma

NOTE  : The presence of a widened optic nerve canal occurs in up to 90% of cases of optic nerve
glioma. While it can also occur in meningioma, it is more common in glioma and some cases of
meningioma may even have a narrowed canal secondary to bony hyperostosis. ( usually asked in FRCR 2A - Module VI).
