Ruptured anterior communicating artery aneurysm causing bilateral abducens nerve paralyses--case report.
A rare case of bilateral abducens nerve paralyses after rupture of an anterior communicating artery (AcoA) aneurysm occurred in a 56-year-old female after sudden onset of severe headache. Bilateral abducens nerve paralyses were present without additional neuro-ophthalmological signs. Computed tomography revealed subarachnoid hemorrhage (SAH). Angiography showed an AcoA aneurysm (15 mm in diameter, directed antero-inferiorly) that was successfully clipped. Postoperatively, the bilateral abducens nerve paralyses gradually recovered and disappeared 3 months after onset. Bilateral abducens nerve paralyses may occur after SAH due to ruptured AcoA aneurysm, and neurosurgeons should be alert to this possibility.
