title: Computed tomography and magnetic resonance imaging of an infiltrative lesion of the anterior visual pathways.
abstract: Infiltrative lesions of the optic chiasm and optic nerves are uncommon. The authors report such a case and discuss the differential diagnosis, paying particular attention to imaging. In the reported case high-resolution computed tomography and magnetic resonance imaging revealed thickening of the optic chiasm and intracranial optic nerves, a pattern characteristic of an inflammatory or neoplastic process.
