We report here a patient with proper name anomia following subcortical hemorrhage in the left superior temporal gyrus. Despite the preserved ability to retrieve common names, the patient could not retrieve the names of people, countries, or racehorses, which he could recognize quite well. Semantic knowledge regarding people, countries, and racehorses was also preserved. In addition. the finding that phonological cueing was effective with preservation of the ability to point to photos corresponding to their names suggested that the lexicon of proper names was preserved in this patient. Thus, the output lexicon appeared to be partially disconnected from semantic knowledge. This rare and limited lesion suggested that the superior temporal gyrus plays an important role in connecting semantic knowledge and the output lexicon.
我们在此报告一名患者，其在左侧颞上回发生皮质下出血后出现专名命名障碍。尽管患者仍具备检索普通名称的能力，但他无法说出他能清晰认出的人的名字、国家名或赛马名。关于人、国家和赛马的语义知识也得以保留。此外，语音提示对保留指向与名称相对应照片的能力有效这一发现表明，该患者的专名词汇表是保留的。因此，输出词汇表似乎与语义知识部分脱节。这种罕见且局限的病变表明，颞上回在连接语义知识和输出词汇表方面发挥着重要作用。
