Phenomenology is the philosophical study of experience and its core feature of sentience, the very ability to be conscious of a sensation and how we perceive it. Nowhere is this idea more vivid, as in the phenomenon of vision and the ability to form and sense a visual percept. The clinical entity of prosopagnosia, the ability to sense but not recognize a face, strikes at the heart of this phenomenon. We describe a classic case of selective apperceptive prosopagnosia due to an ischemic infarct of the left occipital lobe with extension to the lingual gyrus. It is well-established that acquired prosopagnosia usually involves the right more than the left occipital cortex, with localization of lesions bilaterally more than unilaterally. The ischemic infarcts strategically involve the fusiform gyrus, inferior occipital gyrus, the fundus of the posterior temporal sulcus, parahippocampal gyrus, and, rarely, lingual gyrus, which is almost always not a solitary finding. We seize upon this opportunity to explore the concept of visual prosopagnosia and outline the latest ideas on the neuroanatomical localization, neurophysiology, and classification of this intriguing phenomenon.
现象学是对经验及其核心特征——感知能力（即意识到一种感觉并知晓我们如何感知它的能力）的哲学研究。在视觉现象以及形成和感知视觉感知的能力方面，这一观点体现得最为生动。面孔失认症这一临床病症，即能感知但无法识别面孔，直击这一现象的核心。我们描述了一例因左侧枕叶缺血性梗死并累及舌回而导致的典型选择性统觉面孔失认症病例。众所周知，后天性面孔失认症通常更多累及右侧而非左侧枕叶皮质，双侧病变的定位情况多于单侧。缺血性梗死策略性地累及梭状回、枕下回、颞后沟底部、海马旁回，且很少累及舌回，舌回几乎从不单独出现病变。我们借此机会探讨视觉面孔失认症的概念，并概述关于这一有趣现象的神经解剖定位、神经生理学及分类的最新观点。
