Arterial supply and venous drainage at the foramen magnum is variable. Two main forms of clinical presentation, intracranial and spinal, can be differentiated when a dural arteriovenous fistula (DAVF) is found at this level.
We describe a case of a 68-year-old patient with a progressive paraparesis, diagnosed of dural arteriovenous fistula located at the posterior lip of foramen magnum. We review, in this setting, the vascular radiological anatomy of those fistulas and its important correlation with neurologic clinical symptoms.
El aporte arterial y el drenaje venoso en el agujero magno son variables. Dos formas principales de presentación clínica, intracraneal y medular pueden ser diferenciadas en las fístulas durales arteriovenosas encontradas a este nivel. Se presenta el caso de un paciente de 68 años que, tras un cuadro de paraparesia progresiva, se diagnostica de una fístula dural arteriovenosa dural localizada en el borde posterior del agujero magno. A propósito de este caso se revisa la anatomía radiológica y vascular de estas fístulas y su importante correlación con los síntomas neurológicos.
