Carotid Artery Aneurysm: A Rare Cause of Hemotympanum.

Temporal bone fractures can occur as a result of various head trauma. The most common cause of the hemotympanum is traumatic temporal bone fracture. Facial paralysis and hearing loss can be seen associated with temporal bone fracture. The development of the internal carotid artery aneurysm after temporal bone fracture is extremely rare. In this article, the authors evaluated carotid artery aneurysm that developed after temporal fracture and aneurism compressed by coagulated blood mass which showed itself as a hemotympanum. The internal carotid artery aneurysm that induced by temporal bone fracture and presented as hemotympanum has not been reported yet. This patient is the first case in the literature. Diagnosis, treatment, and follow-up options will be discussed in the light of current literature.
