【摘要】 穹窿脑梗死也被称为胼胝体下动脉遗忘综合征，是一种以记忆障碍为主要临床表现的特殊部位脑梗死，其在影像学上容易被忽略，因此当患者出现突然记忆力下降时，应注意是否有穹窿脑梗死的可能。穹窿由前交通动脉的分支胼胝体下动脉供血，胼胝体下动脉为单支动脉，其闭塞常导致双侧穹窿梗死。本文报道1例以记忆力下降为首发临床表现的双侧穹窿急性脑梗死病例，并结合文献总结了穹窿脑梗死的临床特征。更多还原

【Abstract】 Fornix infarction, also known as inferior callosal artery amnesia syndrome, is a special cerebral infarction with amnesia as the main clinical manifestation. The fornix is supplied by the inferior callosal artery which is a branch of the anterior communicating artery.The inferior callosal artery is a single artery and its occlusion often leads to bilateral fornix infarction. We report a case of bilateral fornix acute cerebral infarctions with memory loss as the first clinical manifestation. We also summarize the characteristic of fornix infarction combining literatures. Infarction of the fornix should be included in the differential diagnosis when patient present with acute onset amnesia because it is easily ignored in cerebral imaging.更多还原
