Presentamos un caso de malformación arterio-venosa dural (MAVD) a partir de ambas arterias etmoidales anteriores, diagnosticada mediante RNM y angiografía. El nidus estaba situado a nivel de la lámina cribosa derecha, con drenaje a través de las venas piales trombosadas hasta el seno longitudinal superior. Se extirpó completamente durante el acto quirúrgico, sin secuelas. Se discuten la etiología, la clínica y las posibilidades de tratamiento quirúrgico.
