  • Title: [Symptomatic venous congestion of the brain stem after embolization for dural fistula of the cavernous sinus].
    Author: Grégoire A, Portha C, Cattin F, Vuillier F, Moulin T, Bonneville JF.
    Journal: J Neuroradiol; 2002 Sep; 29(3):183-8. PubMed ID: 12447142.
    Abstract:
    We report the case of a 60-year old woman presenting, 3 days after arterial embolization of a dural arteriovenous fistula, with diplopia and gait disturbance in relation with right oculomotor nerve palsy and cerebellar dysfunction. On T2 weighted MR images, several hyperintense areas appeared in the pons and the midbrain. After one month, clinical symptoms and diffuse hyperintense areas resolved spontaneously, as the patient was treated by anti-vitamin K. This complication probably corresponds to reversible pontine venous congestion caused by poor venous drainage of the dural arteriovenous fistula.
