Lexical agraphia is thought to result from impairment of the lexical spelling system and is characterized by better spelling of nonwords and regularly spelled words than irregularly spelled words. Previous reports have suggested a localization of this syndrome in the region of the left posterior-superior angular gyrus and parietal-occipital lobule, sparing the supramarginal gyrus. We describe a right-handed man who after open-heart surgery displayed lexical agraphia without aphasia, alexia, apraxia, or Gerstmann's syndrome. Computed tomography disclosed a lesion not on the left but on the right in the posterior parietal-occipital region.
词汇性失写症被认为是由词汇拼写系统受损所致，其特征是对非词和拼写规则的词的拼写能力优于拼写不规则的词。先前的报告表明，该综合征定位于左后上颞回和顶枕叶区域，缘上回未受影响。我们描述了一名右利手男性，他在心脏直视手术后出现了词汇性失写症，但无失语症、失读症、失用症或格斯特曼综合征。计算机断层扫描显示病变不在左侧，而是在右侧顶枕叶后部区域。
