Overview
On Head and neck MRI, optic nerve glioma is characterized by isointense to hypointense mass on T1-weighted MRI, and hyperintense mass on T2-weighted MRI.
MRI
Radiographs no longer have any real role to play in the diagnosis of orbital masses, however if performed enlargement of the optic canal may be demonstrated if the tumor is not confined to the orbit. Additional findings of NF1 may also be visible.
