To the right are MRI images of the orbits. These images show a meningioma on the left optic nerve. A meningioma arises from the meninges covering the optic nerve. It is a mass lesion surrounding the optic nerve. It enhances wonderfully with MRI contrast imaging. Linear bands of enhancement, such as these, represent a tumor encasing the optic nerve.
