Low Grade Glioma of the Optic Nerves, Chiasm and Tracts. T1-weighted coronal MRIs. Note the diffuse enlargement of both optic nerves, the optic chiasm and both optic tracts. One can easily appreciate the infiltration of these structures, especially when compared to an aged-matched normal patient. This is a low grade glioma.

Optic nerve gliomas are the most common tumor affecting the optic nerve. They occur most commonly in children and typically have a benign histology. Clinically, they present with loss of vision of the ipsilateral eye. Proptosis and disk pallor may be present on examination.
