我们报告了一名24岁的男性患者,其癫痫发作的传播模式是通过功能性MRI(fMRI)检测到的,该患者有频繁复发的电图癫痫发作。EEG癫痫发作在左枕叶,随后扩散到左半球,右半球程度较轻。功能磁共振成像显示最初增加的血氧水平依赖(BOLD)信号在左枕极。增加的信号然后传播到右枕后颞区,然后是右和左内侧颞区。功能磁共振成像可以作为研究癫痫发作定位和癫痫发作传播的有效工具。
We report the pattern of seizure propagation as detected with functional MRI (fMRI) in a 24-year-old man with frequent recurrent electrographic seizures. The EEG seizure onset was left occipital with later spread in the left hemisphere and to a lesser extent right hemisphere. The fMRI showed initial increase in blood oxygen level-dependent (BOLD) signal in the left occipital pole. The increased signal then propagated to the right occipital-posterotemporal region, then right and left mesial temporal regions. FMRI can be an effective tool to study seizure onset localization and seizure propagation in patients with frequent recurrent seizures.
