Truncus arteriosus is a rare congenital cardiac anomaly characterized by failure of conoseptal separation resulting in a single arterial trunk supplying both the pulmonary and systemic circulation. Diagnosis has historically been made with fetal echocardiography, and palliative surgery performed frequently in the neonatal period. Cross-sectional imaging is typically reserved for post-operative complications. However, due to lower dose radiation and faster scanners, preoperative CT angiography imaging is becoming more common with the increasing use of cardiac EKG-gated CT angiograms, requiring pediatric imagers to be familiar with the diagnosis of the truncus arteriosus spectrum.
