Abstract:
We are reporting a case with decrease vision of the left eye, convergent strabismus of the left eye and diplopia. The neuro-ophthalmologic exam shows palsy of the left sixth cranial (abducens) nerve. The cerebral angiography exam reveals an aneurysm of the left communicating artery. After the neurosurgical approach and the clipping of the aneurysm, the vision significantly improved and the palsy of the abducens nerve disappears. This is a very uncommon clinical correlation between the abducens nerve palsy and the posterior communicating artery aneurysm.
