Abstract
The effects of wallerian degeneration can be demonstrated by MRI as abnormal signal along the course of the degenerate fibres; they have previously been reported in the corticospinal tract. We report two cases of wallerian degeneration of the right optic radiations due to lesions of the right lateral geniculate body. The anatomy and the MRI visibility of the normal optic radiations are briefly discussed.
摘要
瓦勒氏变性的影响可通过磁共振成像（MRI）显示为沿变性纤维走行的异常信号；此前在皮质脊髓束中已有相关报道。我们报告了两例因右侧外侧膝状体病变导致右侧视辐射瓦勒氏变性的病例。本文简要讨论了正常视辐射的解剖结构及MRI可见性。
