Abstract

Patients with blunt and penetrating traumatic injuries to the skull base and soft tissues of the neck present to the emergency department every day. Fortunately, truly life-threatening injuries to these regions are relatively uncommon. However, when encountered and not correctly diagnosed, these entities may result in severe morbidity or mortality. The radiologist plays a critical role recognizing these injuries, in which findings may often be subtle and the anatomy potentially challenging to identify. Multisection CT and CT angiography are commonly performed to assess these injuries in the emergency department. Vascular injury to the neck may result in dissection, occlusion, pseudoaneurysm formation, or frank extravasation resulting in stroke or death. Airway compromise may result from laryngotracheal injury. Injuries to the pharynx and esophagus may result in perforation. Injuries to the temporal bone may result in vascular injury to the internal carotid artery or facial nerve injury, which would require immediate surgery or intervention to prevent paralysis.^©RSNA, 2019.
