一名患者因左侧颞顶叶血肿出现与遗忘性失语相关的书写困难。阅读、抄写、书写字母正常。听写表现出更好的结果logomes和规则的话，没有正字法的困难，比那些有正字法的问题（歧义和不规则的话）。整体特征表明，一个障碍的词汇系统，其中正字法的话，已知的病人是存在的。音位-字形转换的音位路径得以保留，因为错误通常是音位正确的。最初，我们可以得出这样的结论：视觉形式的词语的语义价值是混乱的。口头拼写、听觉阅读和书面命名也显示出更多的错误，难以正字法的单词。该患者出现词语视觉表征障碍。与少数文献报道的病例比较发现，后者常为遗忘性失语，与我们的病例不同之处在于相关的词汇或语音失读症。病变的一个共同特征是右利手患者累及左侧角回。
A patient presented with dysorthographia associated with amnestic aphasia due to a left temporo-parietal hematoma. Reading, copying, graphism of letters were normal. Dictation showed better results for logatomes and regular words, without orthographical difficulty, than for those with orthographical problems (ambiguous and irregular words). The overall features suggested a disorder of the lexical system in which orthography of words known to patients is present. The phonological pathway of phoneme-grapheme conversion was preserved since errors were usually phonologically correct. Initially it was possible to conclude to a disorder of the semantic value of words in their visual form. Oral spelling, auditory reading and written denomination also showed more errors for words of difficult orthography. This patient presented a disorder of visual representation of words. Comparison of this case with the few reported ones showed that the latter often had amnestic aphasia and differed from our case in the associated lexical or phonologic alexia. A common feature of the lesions is involvement of the left angular gyrus is right-handed patients.
