Ipsilateral wallerian degeneration of the distal optic radiations after infarction at their root

Abstract

A 54-year-old man who developed a left homonymous inferior quadrantanopia showed MRI findings of infarction of the proximal portion of the right superior optic radiations and high T2 signal along the entire distal course of the ipsilateral optic radiations consistent with Wallerian degeneration. Frequently reported in other settings, this imaging abnormality has rarely been described in anterior optic radiation lesions.
