Posttraumatic Pseudoaneurysm of the Temporal Artery

Abstract

This is a case presentation of a pediatric patient with severe head trauma resulting from a motor vehicle accident. The patient had been hospitalized for approximately two weeks prior to a request to review a pulsatile mass that had developed after trauma with sonography. Sonographic imaging showed an enlarged vessel with mixed echos throughout. The diagnosis by sonography with duplex confirmed the pulsatile lesion to be a pseudoaneurysm of the temporal artery with mural thrombus.
