We describe a patient with phonological alexia caused by a small hemorrhage in the posterior-inferior portion of the left temporal lobe. The lesion induced a highly selective impairment of phonological reading without concomitant oral language deficits other than anomia for objects presented in the visual and tactile modalities. We propose that an intact dorsal pathway from inferior visual association areas to Wernicke's area via the angular gyrus could mediate reading by the lexical route, while damage to a ventral pathway disrupted the patient's ability to read nonwords. We suggest further that although visually and tactually presented objects could be recognized and both verbally and nonverbally identified, they could not be named because of a disconnection from the area of word representations.
我们描述了一名因左侧颞叶后下部小出血导致语音性失读症的患者。该病变导致语音阅读出现高度选择性损伤，除了对视觉和触觉呈现的物体存在命名障碍外，没有伴随其他口语缺陷。我们提出，从视觉联合区经角回至韦尼克区的完整背侧通路可通过词汇途径介导阅读，而腹侧通路受损则破坏了患者阅读非词的能力。我们进一步认为，尽管视觉和触觉呈现的物体能够被识别并通过言语和非言语方式进行确认，但由于与单词表征区域的连接中断，它们无法被命名。
