本文报告1例左顶叶小梗塞引起的传导性失语症。病人是一名七十四岁右利手的男子，他于十一月十三日出现言语障碍及右手轻微瘫痪。1996. CT扫描显示左顶叶缘上回有一个小的低密度。在入院后5天进行的标准失语症语言测试（SLTA）显示，在自主言语、命名、大声阅读和重复方面，听觉理解和音素性失语症状得以保留。频繁的自我纠正也被观察到，而重复没有显着受损。在发病后三个月的测试显示，一般流利的语言，但仍然存在偶尔的音素性失语症和自我纠正的语言中断。三年零四个月后，大多数失语症消失了，尽管病人声称他仍然有说话困难。本病例提示传导性失语可由位于大脑弓状纤维的小病变引起。其特点是一般言语功能方面的音位性失语和对目标词的自我纠正。这表明，在连接布罗卡区和韦尼克区的通路中的病变导致由于两个区域之间的接口故障而难以选择准确的音素。
This is a report on the patient with conduction aphAsia due to small infarction in the left parietal lobe. The patient is a right-handed man aged 74, who developed a speech disorder and mild paralysis of the right hand on November 13. 1996. A CT scan showed a small low-density in the supramarginal gyrus of the left parietal lobe. Standard Language Test of aphasia (SLTA) conducted at five days after admission to the hospital showed preserved auditory comprehension and phonemic para-aphasia symptoms with respect to volitional speech, naming, reading aloud and repetition. Frequent self-correction was also observed while repetition was not remarkably impaired. A test at three months after the onset revealed generally fluent speech, while there still remained occasional phonemic para-aphasia and self-correction for the speech disruption. Three years and four months later, most of the aphasic syndromes disappeared, although the patient claimed he still had difficulty in speaking. This case suggests that conduction aphasia can be caused by a lesion, though small, located in arcuate fibers of the cerebrum. The characteristics are phonemic para-aphasia with respect to general speech functions as well as self-correction toward target words. The indicated that lesions in the pathway connecting Broca's area and Wernicke's area causes difficulties in selecting accurate phonemes due to a malfunctioning interface between the two areas.
