一名 53 岁的日本右利手男子患有与左胼周动脉闭塞相关的胼胝体断开综合征。计算机断层扫描证实左侧内侧病变影响扣带回、旁中央小叶、左半球楔前叶，最有可能影响胼胝体。这种大脑前动脉综合征的特点是右侧偏瘫，主要是小腿受累，单侧左侧“断开”失写症，以及左侧单侧“断开”触觉命名缺陷。据我们所知，这是文献中第一例单侧左侧失用症与失写症无关的大脑前动脉综合征病例。该病例也是首例将失语症的汉字假名分离作为孤立性左侧失写症的特征进行报道的病例。
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.
