A 62 year old, right handed man developed a pure agraphia as the result of a left temporal lobe stroke. Isolated writing disturbances persisted for seven months until he had a second cerebrovascular accident resulting in total aphasia and right hemiplegia. A CAT scan obtained four months after the first episode showed a localised dilatation of the posterior portion of the left Sylvian cistern and patchy areas of low absorption in the left temporal lobe. The report supports suggestions that localised damage to the language area can produce a pure agraphia as the sole detectable disorder of language organisation.
一名62岁的右利手男性因左侧颞叶中风出现了单纯性失写症。孤立性书写障碍持续了七个月，直到他再次发生脑血管意外，导致完全性失语和右侧偏瘫。首次发作四个月后进行的计算机断层扫描（CAT）显示左侧大脑外侧裂池后部局限性扩张，左侧颞叶有片状低吸收区。该报告支持了这样的观点，即语言区域的局限性损伤可产生单纯性失写症，作为语言组织中唯一可检测到的障碍。
