Аннотация
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.
