Acquired prosopagnosia is usually a consequence of bilateral or right hemisphere lesions and is often associated with topographical disorientation and dyschromatopsia. Left temporo-occipital lesions sometimes result in a face recognition disorder but in a context of visual object agnosia with spared familiarity feelings for faces, usually in left-handers. We describe a patient with a left temporo-occipital hemorrhagic lesion unexpectedly resulting in a deficit of face familiarity, which could represent a mild form of associative prosopagnosia. Our patient failed to feel familiarity feelings even with very well-known famous faces but had neither visual object agnosia nor defects with semantics or naming of celebrities. This was confirmed even when the patient was re-tested a year later. We speculate that a graded lateralization of face processing could be at the basis of occasional cases of prosopagnosia.
获得性面孔失认症通常是双侧或右侧半球病变的结果，并且常常与地形定向障碍和色觉障碍相关。左侧颞枕叶病变有时会导致面孔识别障碍，但通常发生在左利手个体中，且是在视觉物体失认症的背景下，对面孔仍保留熟悉感。我们描述了一名患有左侧颞枕叶出血性病变的患者，意外地出现了对面孔熟悉感的缺失，这可能代表一种轻度的联想性面孔失认症。我们的患者即使面对非常知名的名人面孔也无法产生熟悉感，但既没有视觉物体失认症，也没有名人语义或命名方面的缺陷。即使在一年后对该患者进行重新测试时，这一点也得到了证实。我们推测，面孔加工的分级侧化可能是偶尔出现面孔失认症病例的基础。
