Abstract:
Oculomotor nerve palsy frequently occurs because of external compression by an internal carotid-posterior communicating artery aneurysm and diabetes mellitus. In addition, pontine infarction, cavernous sinus tumors, demyelinating disease, and autoimmune disorder are well-known causes of oculomotor nerve palsy. However, cases of complete oculomotor nerve palsy by neurovascular conflicts presented with a sudden onset of clinical symptoms are extremely rare. We experienced a rare case of complete oculomotor nerve palsy because of direct vascular compression of the oculomotor nerve by the posterior cerebral artery.
