Abstract
- Unruptured dural arteriovenous fistula (dAVF) manifests various symptoms including exophthalmos, headache, tinnitus, and retro-orbital pain. Transient global amnesia (TGA) is a clinical syndrome of reversible anterograde amnesia. Here, we report a 62-year-old woman with dAVF, manifested as TGA. This case emphasized that the clinicians should stay vigilance to the organic cause of TGA, especially in those complaining other symptoms besides amnesia such as pulsatile tinnitus and headache. Furthermore, our case supports a hypothetical patho-mechanism of venous congestion for TGA.
