Isolated abducens nerve palsies associated with intracranial aneurysms have rarely been reported. Their association with anterior communicating artery (ACoA) is even rarer. Intracisternal clot formation and elevated intracranial pressure has been proposed to be the responsible mechanisms.
Herewith, we report two cases of bilateral abducens palsies following ruptured ACoA aneurysms and speculated the possible mechanisms.
Opening of Liliequist's membrane provides clinical improvement due to CSF release.
Rara vez se ha publicado un caso de parálisis aislada del nervio abductor craneal, asociada a un aneurisma. Su asociación con un aneurisma de la arteria comunicante anterior (ACoA) es todavía más rara. Los mecanismos propuestos son la formación de un coágulo intracisternal y la hipertensión intracraneal
Aportamos dos casos de parálisis bilateral del sexto par, después de la ruptura de aneurismas de la ACoA y discutimos los mecanismos posibles.
La apertura de la membrana de Liliequist da lugar a una mejoría clínica, debido a la liberación de l.c.r.
