A 79 year old man with a twelve year progressive history of prosopagnosia and recent naming difficulty, in whom other intellectual skills were preserved, is described. Positron emission tomography (PET) revealed an area of right temporal lobe hypometabolism, with an additional area of less severe hypometabolism at the left temporal pole. This may represent an example of progressive focal cortical degeneration similar to that associated with primary progressive dysphasia, but affecting the right temporal lobe.
本文描述了一位79岁男性，他有12年进行性面孔失认症病史且近期出现命名困难，但其其他智力技能保持完好。正电子发射断层扫描（PET）显示右侧颞叶存在低代谢区域，左侧颞极还有一个不太严重的低代谢区域。这可能是一种进行性局灶性皮质变性的实例，类似于与原发性进行性失语症相关的情况，但影响的是右侧颞叶。
