Introduction - Pseudoaneurysms are usually the result of blunt trauma leading to laceration of part of the vessel wall promoting extravasation of blood into surrounding tissues followed by tamponade and clot formation. Purpose - To present a case of external carotid artery pseudoaneurysm as a complication of mandibular condyle fracture. Case report - An 18-year-old patient, a motorcycle accident victim, attended the emergency of the Cariri Regional Hospital with a mandibular condyle fracture associated with a coronoid fracture and a parasymphysis, evolving with external carotid artery pseudoaneurysm and submitted to selective embolization. Conclusion - We emphasize that pseudoaneurysms of the external carotid artery present mandibular condyle fractures as rare etiological factors, however a careful analysis of their anatomical characteristics as well as early diagnosis contributes to the prevention of accidents and serious complications in the face trauma approaches.
