Primary intraventricular hemorrhage from dural arteriovenous fistula.
Dural arteriovenous fistulas (AVFs) cause several types of intracranial hemorrhage, but rarely cause primary intraventricular hemorrhage (IVH). We report a 67-year-old man with sudden headache and a long history of a pulsatile bruit who developed intraventricular hemorrhage without any parenchymal hemorrhage. Cerebral angiogram revealed dural arteriovenous fistulas in transverse and sigmoid sinuses. Severe retrograde venous drainage seemed to have caused backward flow into the subependymal veins with their consequential rupture. Transvenous embolization was successful.
