In pure alexia, reading is impaired despite almost normal speech, spelling, and writing. We studied a right-handed man with pure alexia, but no hemianopia. He had more difficulty reading longer words (word-length effect), but had no selective reading impairment in phonologic or semantic analysis. Clinical-CT correlation suggests that (1) left hemisphere visual pathways crucial for reading arise from or pass close to the left occipitotemporal or inferior temporal gyrus, and (2) relevant transcallosal fibers from the right hemisphere course inferior to the posterior horn of the left lateral ventricle before ascending to left hemisphere language areas.
在纯失读症中，尽管言语、拼写和书写几乎正常，但阅读能力仍受损。我们研究了一名患有纯失读症但无偏盲的右利手男性。他阅读较长单词时困难更大（词长效应），但在语音或语义分析方面没有选择性阅读障碍。临床-CT相关性表明：（1）对阅读至关重要的左半球视觉通路起源于或靠近左枕颞叶或颞下回，（2）来自右半球的相关胼胝体纤维在上升至左半球语言区之前，在左外侧脑室后角下方走行。
