Ophthalmalgia and Oculomotor Nerve Palsy associated with Compression of an Atherosclerotic and Tortuous Posterior Communicating Artery: A Case Report

Abstract

A 74-year-old female presented with painful left oculomotor nerve palsy. A cerebral angiogram suggested a left internal carotid-posterior communicating aneurysm. At surgery, the compression of the oculomotor nerve by the atherosclerotic and tortuous posterior communicating artery was confirmed. Aneurysmal change was not found. After the adhesive arachnoid membrane was removed, the compression was released. Postoperatively, the symptoms disappeared.
