Internal carotid artery dissection heralded by an oculomotor nerve palsy: case report and literature review.
Acute oculomotor nerve (CN III) palsies are commonly attributed to microvascular disease or compressive lesions and aneurysms, but may rarely be associated with ischemic large vessel disease. We report a case of an extracranial internal carotid artery (ICA) dissection heralded by CN III palsy with review of the relevant literature. ⋯ Acute oculomotor nerve palsies with pupillary involvement warrant thorough investigation. When routine work-up fails to elucidate an etiology, extracranial carotid pathology should be considered.
