目的 探讨左颞叶病灶与失语表现之间的关系.方法 对2例单纯疱疹病毒脑炎所致的主要表现为失语的患者进行汉语失语检查和影像学分析.结果 以左颞上回后部受累为主者与以左颞上回前部及颞中回受累者失语类型完全不同,前者属于不能分型,而后者为典型的Wernicke失语.结论 颞上回后部受累为主所致失语者听理解障碍较轻,颞上回前部受累为主并累及颞中回可导致听理解的严重受损,左颞叶的不同部位在语言形成过程中起着不同的作用.

英文摘要：

Objective To explore into the relationship between the focus of temporal lobe and the performance of aphasia. Methods Two aphasia cases caused by HSE were tested by means of aphasia battery of Chinese （ ABC ） test and imaging analysis. Results Patient 1, whose focus was mainly at the posterior superior temporal area, presented quite different symptoms from patient 2, whose focus was at the anterior superior temporal area and middle temporal gyrus. The former could not be classified into subtypes, while the latter could be determined as a typical Wernicke＇ s aphasia. Conclusions An aphasic subjected to the damage at the posterior superior temporal area has comparatively minor difficulty in listening comprehension ; the damages at the anterior superior temporal area and middle temporal gyrus may lead to serious damage to listening comprehension; different temporal areas play different roles in the formation of language.
