A 55-year-old right-handed man showed inability to recognize the meaning of non-verbal sounds without impairment of language comprehension after a cerebrovascular accident. His auditory acuity was intact and no other sign of agnosia, apraxia or aphasia was detectable. His errors on a test of sound recognition were acoustic rather than semantic. Brain CT scan showed a small lesion in the posterior part of the right temporal lobe. This case suggests that auditory sound agnosia without language disorder can ensure a lesion confined to the right hemisphere, and that the deficit is discriminative rather than associative in nature.
一名55岁右利手男性在脑血管意外后出现无法识别非语言声音的含义，但语言理解未受损。他的听力完好，未检测到失认症、失用症或失语症的其他迹象。他在声音识别测试中的错误是听觉性的而非语义性的。脑部CT扫描显示右侧颞叶后部有一个小病变。该病例表明，无语言障碍的听觉性声音失认症可由局限于右半球的病变引起，且这种缺陷本质上是鉴别性的而非关联性的。
