Abstract

A 58-years-old man came to the hospital because of progressive intellectual deterioration, gait disturbance and postural instability for 6 months. Neuropsychological tests showed severe impairment of memory and executive functions, and dural arteriovenous fistula of the superior sagittal sinus (dAVF of SSS) was found on brain MRI and angiography. The symptoms were markedly improved after selective transvascular embolization treatments. Even though the dAVF of SSS is a rare cause of dementia, we suggest that it can be one of the treatable causes of dementia.
