Core Tip

Core Tip: Venous aneurysms associated with dural arteriovenous fistula (dAVF) have been generally considered to be developed in the setting of venous hypertension or venous ectasia. However, saccular venous aneurysm in patients with dAVF could develop without preceding venous ectasia or venous hypertension and this situation is very rare. So, its pathomechanism remains unclear in patients with dAVF. In this report, we present rare cases of venous aneurysms in the absence of venous hypertension, and describe underlying unique angiographic features; presence of curved or stenotic portion within long and tortuous draining vein.
