A 69-year-old man underwent successful endovascular treatment of a posterior communicating artery aneurysm that had caused a third nerve palsy. Pupil size became normal within 10 days and ptosis and ocular ductions became normal within 3 weeks of the procedure. Based on the reported recovery rates of third nerve palsy after aneurysmal clipping, recovery may occur more rapidly in patients who undergo endovascular treatment. Further data are necessary to substantiate this hypothesis.
