Malformación de la vena de Galeno en un adulto: diagnóstico por imagen por resonancia magnética

Malformation of the vein of Galen is an uncommon intracranial vascular anomaly that is mainly seen in pediatric patients. It presents with diverse manifestations and variable severity. It consists of dilated deep venous structures in the system of Galen, fed by abnormal arteriovenous communications in the midline. Magnetic resonance imaging and magnetic resonance angiography are better than computed tomography for the study of this condition. The case reported here joins the set of rare cases in which a vein of Galen malformation is discovered in an adult.
