title: [Posterior fossa dural arteriovenous fistula with progressive disorder of cerebellar circulation; case report].
abstract: A rare case of posterior fossa dural arteriovenous fistula with cerebellar circulation disorder is reported. A 64-year-old male was admitted to a hospital with complaints of nausea, vertigo and mild headache. Computed tomography (CT) and magnetic resonance imaging (MRI) revealed cerebellar infarction. Then, he was sent to our hospital. He had complaints of cerebellar signs and nystagmus. Cerebral angiography showed dural AVF of the posterior fossa and occlusion of the left transverse-sigmoid sinuses. Because his condition deteriorated, embolization of the left middle meningeal artery, ascending pharyngeal artery and occipital artery was performed selectively on August 18. Subsequently, isolation of dural AVF was performed on August 19. After the operation he improved and was able to walk with a stick. Controlled angiography revealed the disappearance of dural AVF. This case suggested that AV shunt is essential for the progression of venous infarction.
