Abstract

An 85-year-old man presented with a rare large aneurysm of the extracranial internal carotid artery (ICA) due to acute otitis media manifesting as Vernet's syndrome 2 weeks after the diagnosis of right acute otitis media. Angiography of the right extracranial ICA demonstrated an irregularly shaped large aneurysm with partial thrombosis. The aneurysm was treated by proximal ICA occlusion using endovascular coils. The ICA mycotic aneurysm was triggered by acute otitis media, and induced Vernet's syndrome as a result of direct compression to the jugular foramen. Extracranial ICA aneurysms due to focal infection should be considered in the differential diagnosis of lower cranial nerve palsy, although the incidence is thought to be very low.
