Abstract

Isolated unilateral abducens nerve palsies associated with spontaneous subarachnoid hemorrhage have rarely been reported, and their association with anterior communicating artery is even rarer. We report two cases of unilateral abducens nerve palsies following rupture of anterior communicating artery aneurysms. The aneurysms were successfully clipped, and abducens nerve palsies were gradually recovered.

  FIGURE 1. Radiological findings of case 1. A: Head computed tomography (CT) showing subarachnoid hemorrhage of Fisher's grade 3. B: Cerebral CT angiography. Arrows indicate anterior communicating artery and arrow head middle cerebral artery aneurysms, respectively. C: Brain magnetic resonance image demonstrating no definitive abnormal lesion in the brain stem. D: Postoperative cerebral angiography indicating complete disappearance of aneurysms and no vascular abnormality.

  FIGURE 2. Radiological findings of case 2. A: Head computed tomography (CT) showing subarachnoid hemorrhage of Fisher's grade 2. B: Cerebral CT angiography. Arrow indicates anterior communicating artery aneurysm. C: Postoperative cerebral angiography indicating no residual aneurysmal sac or vascular abnormality. D: Brain magnetic resonance image demonstrating a small amount of fluid collection over the right frontotemporal convexity with unremarkable brain stem area.
