Unusual Presentation of Traumatic Pseudoaneurysm of the PosteriorAuricular Artery Manifesting by Massive Bleeding from the External AuditoryCanal: A Case Report

Background: This report describes the unusual case of massive bleeding from the external auditory canal.Results: We present a very rare mechanism of potentially fatal bleeding. We describe presentation, differential diagnosis, anatomy considerations and management options for this case.Conclusions and relevance: Posttraumatic pseudoaneurysm is almost always a result of blunt trauma. When the pseudoaneurysm is bleeding, it requires urgent angiogram and occlusion.
