title: Aqueduct stenosis due to venous ectasia with a dural arteriovenous fistula.
abstract: We report aqueduct compression by venous ectasia in a 65-year-old man with a dural arteriovenous fistula in the posterior cranial fossa draining into a superior vermian vein. Conventional and phase-contrast MRI showed the aqueduct stenosis and the causative dilated vein.
