A 53-year-old right-handed Japanese man had a callosal disconnection syndrome associated with an occlusion of the left pericallosal artery. Computerized tomography scan confirmed a left medial lesion affecting the cingulate gyrus, the paracentral lobule, the precuneus of the left hemisphere, and most probably the corpus callosum. This anterior cerebral artery syndrome was characterized by right hemiparesis with predominant crural involvement, unilateral left-sided "disconnection" agraphia, and left unilateral "disconnection" tactile naming deficit. To our knowledge, this is the first case in the literature of the anterior cerebral artery syndrome in which unilateral leftsided apraxia was not associated with agraphia. The case is also the first in which Kanji-Kana dissociation of an aphasic nature has been reported as a feature of isolated left agraphia.
一名53岁右利手日本男性患有与左侧胼胝体动脉闭塞相关的胼胝体离断综合征。计算机断层扫描证实左侧内侧病变累及扣带回、中央旁小叶、左侧半球楔前叶，很可能还有胼胝体。这种大脑前动脉综合征的特征为右侧偏瘫，以腿部受累为主，左侧单侧“离断性”失写症，以及左侧单侧“离断性”触觉命名缺陷。据我们所知，这是文献中首例大脑前动脉综合征患者，其左侧单侧失用症未伴有失写症。该病例也是首例报告以孤立性左侧失写症为特征的失语性质的日语假名与汉字分离现象。
