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.

后天性闭经通常是双侧或右半球病变的结果，并且通常与地形失常和色盲症有关。左颞枕病变有时会导致面部识别障碍，但在视觉对象失明的情况下，通常在左撇子中会保留面部的熟悉感。我们描述了一个左枕颞部出血病灶出乎意料地导致面部熟悉度下降的患者，这可能代表了一种轻度形式的联想性更年期。即使是非常著名的著名面孔，我们的患者也没有感觉到熟悉的感觉，但是既没有视觉对象的认知，也没有语义或名人的命名缺陷。即使在一年后再次检查患者时，这一点也得到了证实。
