Spectrum of Magnetic Resonance Imaging Features in Unilateral Optic Tract Dysfunction.

Background: Optic tract dysfunction may be the predominant or only clinical manifestation of an intracranial disorder including mass legion, ischemic infarct, inflammatory disease, and trauma. Documentation of the neuroimaging features of these lesions is limited to reports mostly published before the availability of MRI. This study was undertaken to document the spectrum of MRI features in patients presenting with optic tract dysfunction.
