Mycotic Aneurysm of the Extracranial Internal Carotid Artery Following Otitis Media

Abstract

Mycotic aneurysm of the internal carotid artery following otomastoiditis can manifest as a nasopharyngeal mass. This is a very rarely described condition. The case of a patient diagnosed with a retropharyngeal mycotic aneurysm of the left internal carotid artery following otitis media, treated with exclusion of the mycotic aneurysm from the circulation and transnasal drainage. Infection of the mastoid can spread to the parapharyngeal space of the nasopharynx and damage the carotid artery wall, resulting in an infected aneurysm. There are no guidelines on how to surgically approach those aneurysms. An endoscopic transnasal approach can be beneficial.
