We report a case of acute deafness secondary to bilateral hemorrhages involving the external capsule and extending to both temporal isthmi. The lesions probably disrupted both auditory radiations. Deafness disappeared within 2 weeks leading to a transient auditory agnosia for environmental and verbal sounds. Performance on audiological and neurolinguistic tests were consistent with the hypothesis of a deficit of non-specific auditory processes. Psychoacoustical deficits related to subcortical lesions are very rare and might differ from those due to cortical lesions by the lack of aphasia. The present case and both previous cases with subcortical lesions might suffer from auditory agnosia of apperceptive type. Its characteristics and the role of non-specific auditory processes are discussed using the data obtained from this third case.
我们报告一例急性耳聋病例，其继发于双侧出血，出血累及外囊并延伸至双侧颞峡部。这些病变可能破坏了双侧听觉放射。耳聋在2周内消失，导致对环境声音和言语声音出现短暂的听觉失认。听力学和神经语言学测试结果与非特异性听觉过程缺陷的假设一致。与皮质下病变相关的心理声学缺陷非常罕见，可能因缺乏失语症而与皮质病变所致的缺陷有所不同。本病例以及之前两例皮质下病变病例可能患有感知型听觉失认。利用从这第三例病例中获得的数据，对其特征及非特异性听觉过程的作用进行了讨论。
