Infiltrated retrocrural space following thoracic aorta trauma: CT evaluation.
Four cases of abnormal increased soft tissue density in the retrocrural space associated with traumatic thoracic aorta laceration are presented. Although the specificity of this finding needs further study, the dense retrocrural space sign can aid in the determination of the need for thoracic aortography and subsequent identification of aortic tears.
