BACKGROUND
Dural arteriovenous fistula (dAVF) presenting primarily with memory disturbance is relatively rare and may be diagnosed late. However, symptoms often improve with appropriate treatment, as in our case.
CASE PRESENTATION
A 74-year-old man presented with cognitive decline and, within 2 months, developed gait disturbance, dysarthria, and ataxia, leading to hospitalization for suspected dAVF on magnetic resonance imaging. Angiography revealed a superior sagittal sinus dAVF. The patient underwent surgical disconnection of the dAVF from the superior sagittal sinus, and his cognitive function, paresis, and dysarthria improved, allowing for discharge with a modified Rankin Scale score of 2.
CONCLUSION
In cases with memory disturbance, dAVF should be considered a differential diagnosis, verified, and treated accordingly.
背景
主要表现为记忆障碍的硬脑膜动静脉瘘（dAVF）相对少见，且可能诊断较晚。然而，如同我们病例中的情况，症状通常在接受适当治疗后会有所改善。
病例报告
一名74岁男性出现认知功能减退，并在2个月内出现步态障碍、构音障碍和共济失调，因磁共振成像怀疑为dAVF而住院。血管造影显示上矢状窦dAVF。患者接受了dAVF与上矢状窦的手术分离，其认知功能、轻瘫和构音障碍均有所改善，出院时改良Rankin量表评分为2分。
结论
对于有记忆障碍的病例，应考虑dAVF作为鉴别诊断，进行核实并相应治疗。
