The authors report the clinical findings and CT-scanning results in two cases of alexia without agraphia and review the literature on this subject. Both patients had extensive infarction in the territory supplied by the left posterior cerebral artery and developed severe alexia without agraphia, right hemianopia without color-anomia and one of them presented with transient verbal memory difficulties. In both cases the evolution was very good, with total regression of the alexia after 17 months in the first patient and almost complete recovery after there months in the second one. The authors comment on the causes and possible mechanisms of the alexias, especially of the alexia without agraphia, and suggest that every patient with right hemianopic disturbances due to occlusion of the left posterior cerebral artery be thoroughly studied from a neurological point of view, so that this syndrome can be detected since, notwithstanding its recognized rarity, it seems highly probable that many cases have been overlooked as a result of incomplete examination of the patients.
作者报告了两例失读不伴失写症患者的临床发现及CT扫描结果，并回顾了关于该主题的文献。两名患者均在左侧大脑后动脉供血区域发生广泛梗死，并出现严重的失读不伴失写症、无颜色失认的右侧偏盲，其中一名患者还出现短暂的言语记忆困难。两例患者病情转归均良好，第一例患者在17个月后失读完全消退，第二例患者在3个月后几乎完全康复。作者对失读症，尤其是失读不伴失写症的病因及可能机制进行了评论，并建议对每例因左侧大脑后动脉闭塞导致右侧偏盲障碍的患者进行全面的神经学检查，以便能检测出该综合征，因为尽管其公认罕见，但很可能有许多病例因对患者检查不全面而被忽视。
