We report a patient with alexia with agraphia for kanji after hemorrhage in the left posterior middle temporal gyrus. The results of single-character kanji reading and two-character - (Chinese-style pronunciation), - (native Japanese pronunciation), and Jukujikun (irregular ) reading word tests revealed that the patient could not read kanji characters with -reading but read the characters with -reading. We consider that this -reading alexia was caused by disconnection between the posterior inferior temporal cortex (orthographic lexicon) and the posterior superior temporal gyrus (phonological lexicon), and preserved - and Jukujikun-reading was realized by bypassing the orthography-to-phonology route by the semantic route.
我们报告了一例左后颞中回出血后出现汉字失读伴失写症的患者。单字汉字阅读、双字 -（中文发音）、-（日语发音）和 Jukujikun（不规则）阅读单词测试的结果表明，患者无法阅读带有 - 阅读的汉字，但可以阅读带有 - 阅读的汉字。我们认为这种 - 阅读失读症是由于后下颞叶皮层（正字法词汇）和后上颞叶之间的断开引起的，而通过语义途径绕过正字法到语音的途径实现了 - 和 Jukujikun 阅读。
