  • Title: Hydrocephalus caused by a venous varix.
    Author: Arantes M, Romão H, Resende M, Costa M, Garcia R, Resende-Pereira J.
    Journal: Rev Neurol (Paris); 2010 Jan; 166(1):104-7. PubMed ID: 19376556.
    Abstract:
    INTRODUCTION: Vascular malformations are uncommon causes of aqueductal obstruction. To our concern, only one case of hydrocephalus caused by a venous varix draining an unruptured arteriovenous malformation has been described in the literature. CASE REPORT: We report the case of a 70-year-old woman presenting with progressive cognitive impairment, gait disturbance and urinary incontinence. Magnetic resonance imaging and magnetic resonance angiography revealed a large venous varix draining an unruptured arteriovenous malformation causing hydrocephalus. CONCLUSION: Although uncommon, it is necessary to consider the presence of a vascular malformation in adults who presented with signs of aqueductal obstruction.
