Abstract

Air embolism is a rare cause of stroke, usually associated with medical procedures, with gastrointestinal endoscopy rarely implicated. Here, we present a case of a patient who experienced cerebral air embolism post-gastroscopy, presenting with aphasia and right hemiparesis due to left M2 occlusion with spontaneous and complete recovery. CT scan revealed a hypodense defect in the left Sylvian fissure, representing a "hypodense dot sign" suggestive of an air embolism. The hypodense MCA sign, previously described in fat embolism cases, could also indicate air embolism, supporting prompt diagnosis and proper intervention.

先天性空气栓塞的大脑中动脉低密度点状征。

空气栓塞是一种罕见的脑卒中病因，通常与医疗程序有关，胃肠道内窥镜检查很少涉及。在此，我们介绍一例胃镜检查后发生脑空气栓塞的患者，患者因左侧M2闭塞而出现失语和右侧偏瘫，随后自发完全康复。CT 扫描显示左侧 Sylvian 裂隙有低密度缺损，表现为 "低密度点征"，提示为空气栓塞。之前在脂肪栓塞病例中描述过的 MCA 低密度征象也可能提示空气栓塞，这为及时诊断和适当干预提供了支持。

期刊介绍： Neurological Sciences is intended to provide a medium for the communication of results and ideas in the field of neuroscience. The journal welcomes contributions in both the basic and clinical aspects of the neurosciences. The official language of the journal is English. Reports are published in the form of original articles, short communications, editorials, reviews and letters to the editor. Original articles present the results of experimental or clinical studies in the neurosciences, while short communications are succinct reports permitting the rapid publication of novel results. Original contributions may be submitted for the special sections History of Neurology, Health Care and Neurological Digressions - a forum for cultural topics related to the neurosciences. The journal also publishes correspondence book reviews, meeting reports and announcements.
