[Dementia as a result of dural vascular malformation].
A case of dementia can result from encephalopathy caused by venous hypertension, produced by a dural vascular malformation (DVM). The authors describe one tentorial DVM with sinusal venous drainage and retrograde reflux to the cerebral veins (type II), that originated a leukoencephalopathy, and a progressive demential symptomatology. This demential status partially regressed after surgical treatment.
