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.
一名54岁男性出现左侧同向性下象限盲,MRI显示右侧视辐射近端梗死,同侧视辐射整个远端行程T2信号增高,符合华勒氏变性。这种影像学异常在其他情况下经常报道,但在前部视辐射病变中很少描述。
