We report a patient who developed selective Kana (phonogram) agraphia following an infarct in the left middle frontal gyrus known as Exner's area. He had well-preserved ability for comprehension, reading, and writing Kanji (ideogram). Kana errors consisted of substitution with another letter while the number of target words was well preserved. It is suggested that a dominant middle frontal gyrus lesion can result in agraphia.
我们报告了一例患者，其左侧额中回（即 Exner 区）梗死后继发选择性假名失写症。该患者的理解、阅读和书写汉字的能力均保留完好。假名错误表现为以其他字母替代，而目标词的数量则得以较好地保留。这表明优势侧额中回病变可导致失写症。
