Abstract

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.

上矢状窦硬脑膜动静脉瘘致快速进行性痴呆1例

背景：以记忆障碍为主要表现的硬脑膜动静脉瘘（dAVF）较为罕见，诊断较晚。然而，经过适当的治疗，症状通常会得到改善，就像我们的情况一样。一名74岁男性患者表现为认知能力下降，在2个月内出现步态障碍、构音障碍和共济失调，导致磁共振成像疑似dAVF住院。血管造影显示上矢状窦dAVF。患者接受了从上矢状窦断开dAVF的手术，其认知功能、神经麻痹和构音障碍得到改善，并以改良的Rankin量表评分2分出院。结论对伴有记忆障碍的患者，应将dAVF作为鉴别诊断，加以确认和治疗。
