Arteriovenous malformations (AVM) are usually located superficially in the subcortical white matter, and seizures are one of the frequently seen presenting features of AVM. The diagnosis of AVM is confirmed with various neuroimaging techniques. The present study comprised six patients presenting with seizures and headaches, referred to the neurodiagnostic unit to rule out/confirm epilepsy. All patients showed epileptiform activity on electroencephalography (EEG). Further investigations, such as angiography supplemented with computed tomography (CT) showed AVM. EEG is usually not considered a valuable diagnostic tool in AVM, but our results support the finding that EEG is an extremely reliable investigative tool, and should be supplemented with angiography and CT scan for better localization of AVM.
动静脉畸形（AVM）通常位于皮质下白质浅表部位，癫痫发作是AVM常见的首发症状之一。AVM通过多种神经影像学技术得以确诊。本研究纳入了6例以癫痫发作和头痛为表现的患者，他们被转诊至神经诊断科以排除/确诊癫痫。所有患者脑电图（EEG）均显示癫痫样活动。进一步检查，如血管造影联合计算机断层扫描（CT）显示为AVM。通常认为EEG在AVM中并非有价值的诊断工具，但我们的结果支持EEG是一种极其可靠的检查工具这一发现，并且应联合血管造影和CT扫描以更好地对AVM进行定位。
